+21/+22, achieved most of it in my first run, have had 1 upgrade since the hotfix in over eight hours in the dungeon. Seems the patch had the opposite effect on me to everyone else. Whilst I've spent about ten hours in there, I haven't actually completed a run through, every random group I've had so far has failed on the last boss (three attempts). Not that I was getting upgrades in those runs anyways.
