This is what happened to me and my friend “Krigsmann” after we had done a custom blueprint I made called “Greendale to Parking Lot”, which admitedly is a race intended to be used to break through a wall to enter said parking lot. Nevertheless when we had finished that race, we spawned at the windmills, and then you will see for yourself what happened here in 2 videos (accidentally made the first a clip instead of full video)
Part 1: (30 seconds)
Part 2:(12 minutes 37 something seconds)
thats some trippy stuff 
Could you please submit a support ticket and DM me the ticket number?
We’re looking into this and trying to investigate it further.
Has this occurred more than once?
No, RetroKrystal, this is the first time and hopefully the last, I haven’t had an opportunity to re start the game to see if it’s gone as I have full time job to attend to.
EDIT: How do you submit a ticket, also should I include the video links in the ticket?
EDIT 2: I have submitted a ticket and I have sent the ticket ID to you, RetroKrystal in PM.
