The problem I'm having is that it won't progress past trying to create a user profile, it fails and just automatically keeps trying.
I read that this is likely a regression so I think it might have worked in a previous version.
I might try an older version to see if I can get a save working then back that up.
EDIT: I'm an idiot, i did just have to let it fail three times as it was trying to autosave three different things.
