It seems that steam downgraded his version to 1.1.6 again after he installed (maybe manually bypassing steam?) and played 1.1.7.
1.1.6 then detects a savegame from a newer version.
Sorry, I thought the log with give all the information
I updated to the 1.1.7 and the game would crash a couple of seconds after the game loaded, I think it might be when a bot would jump out of my pocket to complete a task.
I have since then downgraded my version to 1.1.6 that didn't crash.
To be more specific:
The second log shows that you tried to open a 1.1.7 save with the 1.1.6 game.
So the assumed "crash" might actually be a controlled (and correct) error message telling you that the savegame could not be loaded.
