Your Actions

Player was exploring new chunks in the Nether and logged out, upon relogging the server crashed and now crashes any time they attempt to log in. My thought for a possible cause is that the chunk was corrupted due to player log out during generation, but I'm not familiar with how minecraft chunk generation works or how it could be affected by other mods.

Crash Report

I've gotten three crash reports after attempting different things to resolve the issue. Report 1
