The sector ghost slides where the sector actually went

Browse Source 
The relocation flourish corrected its coordinates against the view —
but effects are mapped when the events arrive, one message before
the new state, so the correction read the PRE-move board and the
ghost slid between unrelated squares. The sectorRelocated event now
carries its origins in final coordinates, computed after the maze
renormalizes, and the flourish trusts the event alone.
