If you place a ghost object, then rotate it, then undo, the ghost is removed, not unrotated. This is very odd when placing a row of belts and rotate one part way thru (maybe by accident) then undo and the last belt placed is removed rather than the rotation being undone.
Undo does work properly if the object is overwritten by a rotated version (see belt example above, except place a rotated belt in the middle of the line then undo).
[1.1.34] Rotate ghost does not undo
Re: [1.1.34] Rotate ghost does not undo
Then should undo work on a rotation caused by overwrite? The two are functionally identical despite being sourced from different actions, yet they react differently to undo.
