I worked around this by making a Spawner class that spawns on BeginPlay. At least until fixes it.
@ - Is there a way to figure out which side of a corridor the corridor padding is on? I want to rotate the ceiling tiles for the padding areas by 180 around Z-axis when it’s on the opposite side.
Also it seems like the Selector stuff overrides the affinity setting - is there a way to make it still obey it?
