I wish I knew why it was happening, but in 3 of my 4 worlds it is still happening. I did finally notice in the worlds that it does happen the areas were copy/pasted from another section that was already made, and the one where it works the area was moved, not copied over. I did try making them in a totally new area and it still did it. https://youtu.be/i5UK8ugQZm0s I don't know if it will help, but here's an older version of the map I was on Zoo Train .
