Spawner code does not rotate the exit offset along with the facing.

[GraionDilach]

Engine/OpenRA.Mods.AS/Traits/BaseSpawnerMaster.cs

Lines 215 to 218 in a643391

	var spawnOffset = exit == null ? WVec.Zero : exit.Info.SpawnOffset;
	slave.Trait<IPositionable>().SetVisualPosition(slave, centerPosition + spawnOffset);
	var location = self.World.Map.CellContaining(centerPosition + spawnOffset);

The most worthwhile refactor sounds like to turn SetSpawnedFacing into a function returning this value because it already does the syncing between the spawner and the spawnee.
