I have another small problem: sometimes when I change something in level layout controller doesn’t spawn properly on start play. There is a ‘split screen’ with view from both eyes instead of one and position tracking doesn’t work. To fix it I need to pull the start position in to the air but then I’ll start with feet above ground 
When I drop the start position back to ground again it sometimes fixes the problem but not always. Had same problem in two projects so far. I suppose it has something to do with collisions but didn’t exactly find out what’s going on and can’t replicate this on purpose
