Save and quit results in error

Whenever I try to save and quit my world, the game crashes completely and returns me to the home screen. When loading up again i get the message global resources failed to load previously.

Auto save works fine and I usually wait for auto save to finish before quiting. But sometimes that cam take a while.

Switching between worlds is a nightmare.

Very sometimes it does save correctly, but then results in error when trying to load the world again.
