What happened?

The game suddenly started crashing during boot whereas yesterday it was working perfectly fine. I didn't add any mods or made changes in configs. It also doesn't generate a crash log file, so all i can do is copy-paste the fatal error from the Minecraft game output.

crash-log

Game doesn't generate a crash-log file, so i'll just copy-paste the fatal error message here:

same issue. i solved it by downgrading structure essentials library to version 3.4, since it was one of the last mods i had updated

Okay, i am stupid, because i DID update that one exact mod on my WIP modpack today and completely forgot about it. Now i downgraded as well and the problem is gone.

Should i keep this issue open so that others can see it immediately before trying to report the same issue?

getting the same error. (got it to work by changing my strucure essentials to 3.4 cause before i just straight up was disabling it cuz i thought that'd fix it, IT DID NOT, but ye.

nvm its broken again, for literally NO reason.

will be fixed soon

will be fixed soon

not to be rude or rushy, but when is soon.. its been 3 months

Ive been caught up with college, apologies. It'll be done between now and the heat death of the universe

seems like updating structure essentials fixes the problem, also youwereslain mod vertigo and particleeffects make enhanced celestials fail on boot as well.
