Getting rid of precached shaders changed... something? Anyway it crashed in a different spot. And when I say a 'different spot' it started crashing here instead of in an earlier area. Not helpful since this is where it started crashing at first. I'd have the occasional crash elsewhere, but this would always be the farthest I could get.

Not caught in the clip is the screen going gray, which I think could be the Unity crash handler. But the game window would go completely gray so I usually don't see my character disappear like that.
