The bug
Eight misrotated blocks in snowy_temple_1.
Careful when you try to reproduce this - the misrotation is not visible until you look at it through the debug screen. Then you should see 8 blocks that are not rotated by axis Y.
How to reproduce
/setblock ~ ~ ~ structure_block{mode:"LOAD", name:"village/snowy/houses/snowy_temple_1"}
I can't reproduce this with either the example in this report or by manually using a structure block.
Please clarify on how to reproduce.
