This error showed up while loading a save from 0.20 If I delete all my old saves from 0.20 the error doesn't show. This also doesn't happen with new saves in 0.23. I'll go and put the save files in an email for you.
Thanks. I fixed the issue and your old saves should work again. Unless some new bug pops up. I uploaded the new version. It's exactly the same as the old one, apart from the save fix and improved save screen you could see in the sneak-peeks.
