Oh, I see! In effect, this error is saying "an entity is being assigned an animation state they don't have", so I am 99% sure what's happening- the level-end crystal is being given something incorrect and causing the issue. Then, when closing the console, the game continues as normal, having skipped the "load crystal" routine, so you enter the empty area where there should be a crystal, but it's missing. Since level completion is tied to destroying that crystal instead of any loading zone, this means the levels are unbeatable right now... whoops!!!
I will have this fixed by the end of the day tomorrow- gimme like 24 hours
