Crash on dedicated server startup, 1.20.1, Forge 47.3.7, Curseforge

[muppetenergy]

Server crashed a couple times over the past couple days on startup. It started up again seemingly ok, but we've had a few crashes that no one has been able to figure out. Two of these say Quark loaded incorrectly, but I'll include the others in case they are useful.

I'm suuuuuuper hoping to avoid restoring from a backup, especially not really knowing what's causing the issues.

The latest log may not show very much since I've done a lot of restarting the server trying to troubleshoot.
Please let me know if I can provide any other info, thank you.

The curious part is, all I have to do is start the game a couple times, often the 2nd time around is enough, sometimes it takes 3 or 4 starts for the game to start up.

Edited these comments to a checklist, the ones I've checked-off are caused by VazkiiMods/Zeta#52 and that should be fixed in the latest versions of Quark and Zeta, go grab em. Sorry for the trouble.

The other two, no idea, quark isn't mentioned anywhere in the stacktrace but ofc we do a lot of worldgen so it could be us :)

  This looks like a multithreading-related crash. If this was on startup, it's possible the latest versions of Quark and Zeta (which have some threading fixes) could be related.

  This just looks like a server lagging out after running /locate. This could be some kind of deadlock bug, but if your server frequently gets slow when doing worldgen, could also just be lagging.
