I was playing normally all day yesterday when my game suddenly bugged out and caused me to be invincible. I even restarted my computer and it consistently kept making me invulnerable after a min of playing. On top that the ability to upgrade the quality of legendaries was unavailable saying its the wrong item for the slot when I clearly did it many times before. I could however upgrade the rarity of the legendary which is pointless as it literally does nothing. Last patch it was mentioned that this issue was fixed but i think you guys made a mistake and confused the two.
