How to reproduce

Create a cube, manually place mouse ears at the four corners, Right click > Add instance to create a second cube, move the cube away from the initial one, rotate the new cube. Slice the plate and the new cube's mouse ears are either incorrectly placed or completely missing.

Actual results

The mouse ears on the copy will be either misplaced or completely missing.

Expected results

Mouse ears should be the same as the original cube. If the second cube isn't rotated, the mouse ears are fine. But once rotated they're either misplaced or missing altogether.
