Crash Report

Based on the crash report, it looks like this.puffbug.getLaunchDirection() here returned null, then it crashed when attempting to use it as a vector. I was just tabbed out while idling in The End when it crashed, doesn't continue crashing upon reloading the world and can't reliably reproduce the crash so no ideas on how it got into that state to begin with.

Ping, this is still a nasty problem crashing servers.

Had this happen an additional 3 times so set up a test environment to see if it was a weird mod interaction or smth. Got the crash with only Endergenic and Blueprint installed so it's something that can happen regardless

Can confirm this is the only issue that has crashed my entire modpack server. Please look into it.
