Hello densch :)
First thank you for playing the game!
Do you remember where/when in the game you encountered this error? That would help me a lot in fixing it! The game is huge, so knowing that a float division error exists somewhere in the game is not enough information, I hope you will understand :S
I check the first 10 minutes of the game each time I release a new version, I also do random stuff with my own save, but did never encounter that one :O
