nah, was a very minor issue of trying to do too many things at once (again) while not having exited the game (or photoshop, or word, or a couple other things with a video playing off and on in the background) in about 3 days. >.>

Then I added more stuff to the already packed lot, moved in a bunch of sims, unfroze him and ... display error.

Quick restart and its all better now! I'm thinking maybe not the best idea to leave things that long again though.
