The bug

One block in the structure minecraft:village/taiga/houses/taiga_butcher_shop_1 appears to be rotated incorrectly. Normally, this block is not visible, but upon removing a layer from the roof of the structure, this block can be seen.

This screenshot represents the complete roof of the structure:

This screenshot represents the roof of the structure with the four logs on the top layer removed, exposing the incorrect log (outlined):

How to reproduce

1. Click the LOAD in the bottom right corner once to show the outline of the structure
2. Click on the structure block and click LOAD once again to load in the structure
3. Open your F3 debug menu
