I have the jumping bug to but only on downtown lots, I also have the new NL no auto napping, I am going to take it out and see if that works.
I just hate going through all my hacks and taking them out one at a time, besides I am only using hacks that have been approved except for the "no eat crap" and I know it is not that one because I have been using it since I installed NL and before I got that damn jump bug.
thanks for the telling us about the no autonomous napping problem saved me a lot of work.
