Ok, well I haven't run into any PZ3 bugs, but I have turned Sydney into Gumby in the cloth room when I added a second Dynamic cloth item to the scene. 

First Item: Dynamic Pants. Run Simulation. Perfect Fit.
Second Item: Dynamic Shirt: Falls through figure even though Collisions are turned on for the entire figure. Hitting cancel and redoing collisions doesn't fix it and eventually the cloth room begins to Clothify Sydney and first it was a rubber neck where her head shot up through the roof, second it was her right arm going all rubbery.
