It looks like you are hitting some form of recursion. The first 2 worlds seem to work ok but when you delete one and spawn the next I’m suspecting you maybe missed something in the cleanup process during destroying worlds. Your camera starts jittering like it has two conflicting rotation information inputs.
Could it be that part of the deleted world is interjecting into the newly created one causing some sort of feed back look that ends in a recursion error once it hits a limit?
