I encountered a strange thing, when I join my main save(in custom dimensions), the world stopped, everything stopped, only less chunk loaded, Save and exit will get stuck. So no logs and crash-reports spawn. I try many times, It looks stop from the windmill auto tree farm loaded.
Then I try copy the region file to other saves overworld. But it works normal. I stopped the tree farm and savegame, then copy back the region file, Problem solved.
Heres the region file.
