The game crashes upon attempting to play on or create a world. This was tested in two ways.

1. A world was created and played with Quark disabled, but with AutoRegLib enabled. Then Quark was enabled, and the world was attempted to be played on.
2. A world was attempted to be created with Quark enabled.
   The game also crashed upon changing Forge to the latest recommended version that I could tell (34.1.0)
   It works fine with AutoRegLib, even with my other mods (though ones that don't require it). It appears to be impossible for me to play Minecraft with this version of Quark.
   Some config options for Quark were changed within the in-game menu. I'm not sure if this is relevant.
   I don't see any reports of this on github, which leads me to believe that this is a rare issue. However, these crashes are consistent to me and have little variance, if any, outside of the ways they are encountered.
   This is my first time ever reporting an issue for anything, so I hope this information is helpful. If anyone is aware of a fix, I would love to hear it.

AutoRegLib: 1.6-46
Quark: r2.4-269

You just ran out of memory. There's a big memory issue in the latest release version of quark, so do give it a test again after I release the next one.

Quark r2.4-270 fixed the issue completely, and I can play with it now. Thank you! I'm sorry if I seemed to overreact in my report, I didn't know what I was supposed to look for, so I gave all the information I could. Very happy to be able to play with Quark again.
