Two things I noticed by accident that might need some tweaking:
- While repairing two blades of the same kind I hit my dequip shortcut when I was done with the first. It piled up with the one that wasn't repaired yet. Suddenly, the 50/50 quality one and the 30/50 quality one were shuffled together, both ending up with 44/50 quality.
- While swaping items between alts, I went behind a secluded corner in town and dropped two 0/50 quality blades, logged off and on again as another character and the quality had been reset to 50/50.
