Howdy do we do?

Big overhaul as the server was crashing and lagging like hell. :)

Current startup line on linux:

java -d64 -server -Xms4096m -Xmx8192m -XX:MaxHeapSize=8G -Dfml.readTimeout=120 -XX:MaxNewSize=64m -XX:NewSize=64m -jar forge-1.12
.2-14.23.5.2815-universal.jar nogui

Mods were also updated, betas (except Thaumcraft6) removed.

You can make a soft-restart by transferring the following directories from the world-directory:

advancements

playerdata

stats

into an empty one.

Take care to go high up, or you may have the chance to respawn under inside the ground of the new generation.
