The bug
Ten misrotated blocks in snowy_library_1.
This is the same misrotation as in snowy_temple_1, (not visible until you look through the debug screen) which is MC-177623.
It can be seen in the screenshot. And if you look closely, it is visible.

And how did that misrotation even happen? An accident with the debug stick?
