Offline bounce crash, probably Waves-related, and offline bounce not 100% correct

[Skwaidu]

So as per title, anyone else have this? Offline bounce seems to work ok until I insert *one* Waves plugin in to the session, then PT crashes. Even with only 1 stereo audio track. I have the newest Waves versions, Platinum and SSL Soundgrid license (but using just the Native versions).

And on that note, even when offline bounce works it does *not* always work 100%. I have a quite complex master setup on some of my mixes including a processing 2buss with McDSP, Slate, Massey etc and a parallel chain of DUY's DaD Tape (one aux with plugin, one without) after that, if I try offline bouncing that (without any Waves) I get a level difference in the result. I'm thinking it could be the DUY chain as that's the most "esoteric" in my setup, but the fact is that Avid doesn't have it 100% right (unless it's DUY, Slate, McDSP, Massey or someone else bugging out in offline).

Anyone else have these problems with Waves (or anything) crashing offline bounce or offline bounce not being 100% faithful to the mixer?
