Yes, I always use the lastest version.

It's not a forge bug, I never used forge or any mod in my map, and it bugged when I joined in 1.12...

I installed forge and it fixed! But if you unistall forge it will be bugged again! So you must use forge version until Mojang fix it.

Yeah Conrad Herman, it bugged my universal tree farm and my tnt blast chamber too 😞
