Although your error log is not identical to the ones I keep getting from SW, it may still be related. It seems that Paladin posted something about the Servo chore controller not quite working correctly with Seasons. I get error logs from that and the Servo security system. It may be the robot trying to get smart milk for a toddler.
He has a place to get help with his items now:
http://support.simwardrobe.com/But don't expect the calibur of support that you get here. I posted the error logs that come up repeatedly in my game on June 13. He still has not responded.
ETA: There is also a sticky post there about the playable maid controller being buggy after Seasons. I don't know if it is fixed or not yet, as it is an item that I don't use.
