To add onto this, I also experienced the infinite soda bug, and had traps that would just reappear after a short time. I think desk items also just don't go away cuz I had soapy water stay as well, you can't place another desk trap in those situations.
And I do have to agree with the OP on the hitlist, tankiness of non-interns, and general confusion in trying to figure out what some things mean. I do appreciate your work!
