Upgraded to 1.16.4
I finally decided to upgrade to 1.16.4 after seeing that all the plugins I like could support 1.16.4.
Getting an Upgrade
Believe it or not, I upgraded the network's hardware. I replaced the Dell Optiplex 9010 SFF with i3-3770 with a Dell Optiplex 7070 MFF with i7-9700T. Here are the full details of the new system for the curious:

Migrated back to a home-hosted server
I have moved the entire Wulfenrat Network off of a professionally-hosted server and on to a "physical" server that resides at my residence. This means that the connection will be weaker, but also that there will never be RAM or disk space limits/concerns to contend with.

Some of the old-timers will remember that the network/server started out as a home server and I changed to a professional host to keep the server up while I moved from Kentucky to Missouri.

The connection to a home-hosted server becomes a bigger deal when there are a lot of people connected, but we have not seen many players connected in a very long time. For your information, the most people we ever had on at one time was about 14 players and that was in November 2015, which was before we moved to the professional host. So I am hopeful that hosting locally again will not be an issue.

Switching to a home server allows me to justify keeping the network alive into the foreseeable future. I was paying a hosting provider about $273 a year for the VPS that was only hosting the Wulfenrat Minecraft Network and the website for the network. Now I will be paying virtually nothing (just the price of electricity). Originally I was paying only about $100 every 6 months, but we were very obviously hitting the RAM limit and I had to upgrade the host VPS resource allocations (going from $200 a year to $273 a year).

If you have any trouble or questions, please reach out to me (RuggedSurvivor) on our Discord.

More VPS/network updates
A couple of days ago I found some solid evidence that the server crashes we were experiencing (and perhaps other troubles) were due to exhausting total VPS memory. We had 3GB and each Minecraft server on the VPS was set with a max memory limit of 4GB.. whoops, yeah that doesn't make sense. So I paid for 1GB more total memory on the VPS so we now have 4GB, and I also set the limit of memory usage for each server to be 512MB. Since they I have yet to see a server crash. I feel like with the settings and memory we have now, we should be able to run up to 6 servers at a time. Currently we have 4 active servers running: classic, hub, zelda, and fnaf. I hope to add a creative (plot) server soon.

ALSO, just today I have upgraded all the server from 1.12 to 1.12.1. I will update the plugins as I find time. I already noticed that signs copied/cut and pasted with WorldEdit lose their messages, so there are likely other things to watch out for.
ImageOnMap was giving us trouble in 1.12
I disabled ImageOnMap because it was causing memory issues, for the classic server and for the entire network. You can still make maps using the old technique, but maps made with ImageOnMap have been cleared out. I wish there were an alternative. I will try to look into it later, but I am pretty sure there is nothing like ImageOnMap that works in 1.12, yet anyways.
Some improvements on the new network
I got the nicknames working on the new network. The groups/permissions are mostly working, including WorldEdit. :-) The special maps might be messed up but I think that can be fixed. The log parsing is not going to be the same so that is probably going to be messed up for a while. I am just about ready to make the switch.
Rehosting and redesigning the network
I have been working to prepare what will become the new Wulfenrat Network. The new network has BungeeCord, uses LuckPerms instead of GroupManager, has a faster connection, but less diskspace. Currently the permissions and groups are not all configured. Right now nicknames do not work on the new network, and logging is different and so the log parsing that I use to populate player information that is used on the website is going to be broken at least for a while.
Minecraft 1.12 - more color!
I updated the servers to use 1.12 which I think is a great update but somehow 1.12 is not playing nicely with WorldEdit or GroupManager. I suspect GroupManager and I am very seriously considering switching to a different permissions plugin.
Minecraft Version 1.11
I went ahead and switched us to 1.11, but be aware that not all plugins work 100%. For example, WorldEdit does not copy the messages on signs for now. We are already using the latest WorldEdit plugin. I will try to check often for when a new one comes out. I even went on the sk89q IRC to ask if there was an ETA for the 1.11 WorldEdit plugin, but did not get an answer.

The Creative World Borders Expanded
Ry and Dom wanted to find a Stray in the the wild, but there were no Ice Plains within the 5000x5000 (-2500 to 2500) dimensions for the world border. The closest Ice Plains biome was at -3250. I checked that we are only using 42% of our diskspace, and that diskspace is a 500GB SSD.
$ df -h

/dev/sda1                 236M  225M     0 100% /boot
So anyways, I decided to increase the borders to be 10000x10000 (-5000 to 5000), which quadruples the 2D size of the world. This also put a good chunk of Ice Plains and Ice Mountains within the borders, puts that Mesa biome down South all within borders, and also puts some of a Jungle biome (up north) into the borders. If we continue to do well size-wise we can keep these expanded borders. Feel free to explore, but be sensible about what you build. If you start something, finish it, or ask an Admin for help to clean it up. Anything uncovered in the game will show up in the render, but please do not TP outside of the world borders (it will force you back but the game will still render a chunk).
Minecraft Version 1.10
Polar bears! I went ahead and updated the server jars that Creative, Survival, and FNAF use, even though I did not update any plugins. Miraculously, things seem to work from the little testing that I did. Please help us test. If something seems strange report it to me or an admin.
Creative Server Project: The Builder's Training Course
You may have noticed Bean and I working on something up North on the Creative server. It is a new challenge we plan to use for the Trainee-to-Builder rank advancement. It is a "training course" in that the challenger will need to pass stages with which different WorldEdit commands will be taught and tested. Of course passing it will reward a new achievement.
Micro-Challenge added: Eagle Totem
This micro-challenge was created in the Survival server/world, but I may port it over to the creative. It will give you a very cool item, and force you to use it. It will also eventually award an achievement. I do not have that working just yet, but the achievement will be awarded retroactively once I tweak the log parsing to work on the non-Creative servers. If you play in the Survival world, you could try to find it. It sticks out in the rendered map. It is in the mesa biome.
FNAF Roller Coaster Well Under Way
GRT3 and I have been working on the FNAF coaster for several months now. It might be half way done and is turning out awesome. The end result of course will be a YouTube video. Care to help out? Come join us on the FNAF coaster server ("fnaf", port 25570). I would say to check out the rendered map, but that does not do it justice. You have to see/ride it for yourself.
Upgrades! (Minecraft 1.9 and a "cleaned" Creative world)
After a LOT of work from Bean, and a little on my part, we decided we were ready to switch to MC 1.9. We also are switching to a "cleaner" world. This cleaner world is less than 1/30th the size of the old world. The old world was 30GB in a compressed archive. Considering that we take hourly backups, and we keep dailies for several weeks, our 512GB SSD HD was QUICKLY filling up. If you find something missing in the new cleaned world, let Bean or I know. We have the old world running and can pull things in from there if you really need them.
