If it's really going to take 90 real time minutes to reproduce the freeze now, this makes things more complicated to troubleshoot. Yes, of course the game is not going to react well to TS2 package files being shoved at it. Might there be more of this kind of thing in play? Or even recently added proper TS3 content that is passing the Dashboard test but still slowly acting up in-game? Emphasizing recently since this entire issue is being described as something that is new and never happened on such a regular basis before.
And to repeat a prior answer I would still be happy to look at your script logs, but not the ones from before where the game was trying to grapple with TS2 content because those would now not provide very useful information.
