Process exited with code 1.

happens when starting the game after quitting, deleting badoptimizations.txt in the config folder before starting every time fixes it

Somehow I forgot to respond to this, oops.

Perchance do you have the debugify mod installed? I heard some issues with that mod.

Yeah I do

Does it happen without the mod? Somebody else reports the same.

My 2 week mc phase ended so I deleted the mod pack I'll try to remake it

the crash still happends with debugify not installed

A mod crashed on startup!

Did you make sure to delete your config first?

yes

Odd, I've never been able to replicate this myself. Does it happen with just badoptimizations alone?

no

Do you have any idea which mod causes it?

i give up

Do you have any idea which mod causes it?

says somthing about better clouds

Crash_Is_Not_Caused_By_BetterClouds
I presume this has something to do with load order but do you know if it happens if you have all your mods except better clouds?

A mod crashed on startup!

I can't replicate this at all, so my best suggestion would be to start with just badoptimizations and keep adding mods until it breaks.

It might have something to do with prelaunch mods - if you still want to can you try removing betterclouds and c2me?
