I don't think many people use, know, care, etc about the quality stats in the game just yet since they don't do much and aren't talked about
But I found a bug involving them that hopefully is already being worked out and if not, is going to be brought to your attention, now, and its pretty much short and simple and I can't really elaborate on it, so it can go here.
On reload, Items that had quality, forget they had quality, and return to 0 across the board.
Again - Trivial, at the moment, since they're pretty much just for show, decoration, and not use. - but still a bug, that I don't think has been mentioned (glanced for a while over different sections of Trello, haven't seen it mentioned since I started playing (last patch), at least, I don't think I have.
