Did this, and have a batch file that deletes the thumbnail cache before even starting the game, also tried to track down every item that was used in any animation, but have not yet found the one responsible for that stupid info pop up that says Items remove, which there is never anything removed

.
I do know I can drop WW and all thing's dependent on it, and the pop up never happens so it is something to do with WW, I suspect they are checking item matches to animations, to make life easier for the animators, by testing if there item needed for and animation is there, possibly passing over the animation in question if the item is not there.
It is a very bothersome thing or at the very least annoying. As many have said there is no easy way to figure out just what Item you are missing.
I truly hope Turbo comes up with a better plan soon. I fear I will get in the habit of ignoring the problem, and there actually will be a problem sometime that buggers my game save, but as they are using the Maxis debug to there own needs. I will never know.
EDIT >>> Another thing you may have noticed that a lot of People have been plaguing Official forum's with this problem.
I am betting many of these prude's are running WW, but would never admit it. As there back sides do not stink, and these same people probably talk bad about WW. and how they would never run something like that along with other stupid forum threads like "Why would you run WW"
