After completing a quest, I got a pop up saying to visit the shrine to pick up my emblem. I went to the shrine on Adanac and attempted to pick up the emblem while not realizing my bag was full. The message popped up saying that I received it, but it wasn't on the ground nor in my too-full bags. I checked the shrine again but there seemed to be no option to get it.
I'd expected it to either fall to the ground or stay with the shrine, but neither happened :( There wasn't anyone else on the street at the time, so I know no one else picked it up.
