Game crashes when I try to open the player inventory. I looked through the crash report but can't figure it out.
There are a lot of mods in the pack.

Hi I'm the author of the mod you have installed named "Generic Ecosphere"; as of right now, the mod isn't compatible with JEI, though, I am trying to figure out how to fix this as this crash is likely on my end.

Gotcha! I want JEI more than Generic Ecosphere so I'll remove that for now. Thanks!
