So I was building a door and got the recipe like normal (first time btw) and when I opened the little bench it crashed my game immediately

Please hall

Please post the crash report.

I'm a bit dumb on this side of stuff how to I copy a crash report

Your issue is most likely an outdated version of CreativeCore and LittleTiles ...

Does it come in 1.16.2 or what is the latest version,?

I'm using 1.12.2 creative core and forge and little tiles

No it's not updated yet and I wasn't talking about the minecraft version ...

so use 1.16.4 forge ?
or what im a bit confused'
and i can get the crash log if you need me to
