You could have logic that tries to go between two different layouts constantly or keeps refreshing the layout. Or if you messed with timescale then it's stuck at 0. If it's not that I dunno, share the project.
Well, I don't really recall messing with the timescale. Also, these are the events that determine whether the player enters a new level.
When I go into any level (the same or different level) more than once during a preview, the timescale completely freezes. However, the music for the level still plays and the debugger shows that it's in a level. Here is an example:
I'm not sure why this is happening. Not even the save and load feature that I've added fixed this (yeah, crazy).
