Qilin

Steps:
Defeated Qilin then clicked on the Riftworn Pyxis, but nothing happened like it normally would (showing a menu with a list of rewards obtained). My other character on a separate computer had no issues. I'd fought Qilin several times today and had not had this happen before. I'm really hoping it's not because a Corscuanti dropped and the menu glitched, but that seems to be highly likely considering it's the only situation that would be different from what I've been doing throughout the day.

I killed Qilin several times after this occurred and have not seen the same issue. If it was a pulse weapon, the 0.1% drop rate would make it very difficult to replicate.
