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.
