I haven't had any freezes with 7.16 at all, but something happened a few days ago that was very weird, but I'm not sure it has anything to do with 7.16, I selected a patch that I had a harmonizer on, and it played back the wrong harmony notes, between songs I turned it off/on and it still had the same wrong notes out of the harmonizer, after the gig I check it again and went to the Edit Pitch page, to check and it wasn't playing back what I had set up, then I went to another patch that also had the Harmonizer and that one was fine, so I go back to original patch that had the problem and now it was playing the proper harmonies, without me having changed anything.. have used it for a few days after that and everything is fine, so I don't know what happened. This was on an Ultra and the patch was very simple, just Amp > Pitch >Delay > Cab.
