What should I do?

 

EDIT: It crashes when I try to create/join a singleplayer world too.

[Guest Dude322111]

Thanks for all of your help guys, I fixed the crash by removing NEI.

Do you have any saved inv on NEI? Like on your own worlds you saved your inv in cheat mode?

[Guest Nik]

Delete the modpack and reinstall from technic.

[Guest Dude322111]

Do you have any saved inv on NEI? Like on your own worlds you saved your inv in cheat mode?

 

No, this is actually on a different computer than I usually use.

 

 

Delete the modpack and reinstall from technic.

 

I've done that twice, didn't work.

[Alex 1]

Were you in a vehicle on logout?

[Guest Dude322111]

No.
