I think I broke my save or encountered a bug. For one, my sanity no longer decreases, and I also can't starve... But more importantly, the event for disposing of the robot parts isn't triggering.
I threw away one bot part, but for the second one, I decided against it and entered "Bigdaddyhurts." After that, there was a dialogue stating that I would leave a message for Bigdaddy with the next order. Since then, I've bought three bot parts, but nothing has happened.
Did I forget something? (Although, I only threw away the first bot part on day 20...)
