Placement to look identical to schematic.

Reproduction Steps

Place a schematic for builder (Archwood Collective builder hut). Do not touch mirror control. (I may have rotated, I do not recall).
Allow them to build level 1, then upgrade to level 2 (the problem blocks in this build are level 2 portions)

Start by reproducing the Archwood Collective builder hut upgrade on Minecraft 1.21 with Structurize 833, MineColonies 1381, and DO 236, then inspect the linked logs and compare the schematic, item, and placed blocks. Done means the level 2 placement matches the schematic without changing the mirror control.
