F5 bug

There's a bug that breaks the map when you press F5 and run it from a straight cave to a third person view. I've been thinking about it for a long time, so I'm reporting it.

I wrote it in a translator, but I'm sorry if you don't understand.

(You can see if it's night or day. It's easy to see what terrain is nearby.)
