What is this weird sunburst that shows up when I test the live game on mobile, but not in the editor

Ok now the whole thing is just messed up--I can go back to a previous days backup, publish it, and some weird version of the world is live instead of what I published. The most current world which works fine in the editor, when published--none of the character collisions seem to work anymore on device and some objects just straight up don't appear. I dunno...maybe there's some maintenance going on for the live servers?
