Game crashed after exporting world both from world selection and in-game.

Nextbook 11.6

Game crashes right after exporting world, both from the in-game menu and from the world selection. Regardless of whether or not I replace old world file or make a new one, game will crash seconds after export finishes, in addition when I do export, the progress bar is near full as soon as export starts.

Edit: Just checked, last 3 exports are 0 Bytes, game is failing to export worlds. Glad I checked, I have to make manual backups now. Should I try to re-install? Let me know if you need copy of world.
