The thing is, Bob's and Krastorio were not really designed to work with each other. I've fixed what crashes I can find, but there will still be a lot of weirdness due to all the redundancies that exist. New version will be uploaded later today.
Edit: I was not able to reproduce the crash from your first screenshot (data-updates.lua line 86). This crash should not have been possible because that specific line is contained within an if/then that requires part of bobmods that is explicitly incompatible with Krastorio2. There may have been some other mod contributing to the conflict, but I have done what I can to add further safeguards.
