I noticed an Issue in 1.12.2 with Malisis doors.

In minecolonies there is a builder which takes a schematic and exactly copies the blockState to another location. This does cause a lot of issues with malisis doors installed like open trapdoors and wrong placed doors.

You'll have to be more specific. Your report doesn't contain any information at all.

It seems like vanilla blockStates don't get converted correctly to malisis block states correctly
