When i save manualy or automatic, the game chrashs, im on online version, linux mint firefox

This sounds not good, I think it could have something Todo with the compression :/

I walk down the first staircase and it crashes. Probably the same thing.

A bunch of these with ascending data keys at the end

but it looks rather unhelpful

Yeah, I got a bit the reason why it crashes but need now to work around it and it takes a while
