So I'm playing a modpack called MC Eternal(1.12.2) and I'm trying to make Little Tiles doors but when I try to activate any kind of door by right clicking it my game crashes,I tried switching to the latest version of Little Tiles(+CreativeCore) but that didn't solve anything so I'm gonna post a crash log here :)
Crashlog.txt

I tried changing some video settings in game just in case it gave different results but it didn't help,posting second crash log just in case, hope it helps
Crashlog2.txt

It's caused by another mod, but I don't know which one. Probably a mod which changes some stuff regarding worlds. I guess there is no other way than to test which mod is causing it.

Oof,I thought it might be a compatibility issue between mods,I guess my suspicion was correct, but this pack has so many ah well thank you anyway I will try finding out which one it is :D

You know the trick? Remove half of the mods and check if it still works? It's a very annoying process I know.

That's what I was thinking 😅

Alright after like 3 hours of testing I have found out that Valkyrien Skies mod was causing the crashes.

Oh damn ... I'm soo sorry, I have looked through the mod file and missed that one. I could have told you this earlier. Damn ... I should have looked more closely. There is a also a very outdated mod compatibility list: https://github.com/CreativeMD/LittleTiles/wiki/Mod-Compatibility

It's alright I had nothing else to do anyway,I have looked at that compatibility list btw :D
