18 days, no reply, I’m feeling your pain:
How many player starts do you have in your map and are they at the positions for where you want each players’ controller to start?
Or maybe just set empty scene actors at the locations and aligned as you desire for them and spawn the players there, one-by-one, setting the spawn locations/rotations to match the empty scene actors location/rotation?
Maybe at BeginPlay(), set that controller’s/pawn’s actor to the location/rotation at that time?
Most likely, you will have to keep experimenting until you get what you are looking for.
