hideout crashing on export/import (cosmic turtle)

I'm using the cosmic turtle hideout and it's crashing when I try to save an export for it. It's also crashing when I try to import a file using the cosmic turtle hideout. I admit I haven't tried exporting/importing other hideouts recently (mainly because I'd like to save the one I currently have).

Bumping this, also getting the same behaviour importing hideouts for Cosmic Turtle Hideout
