Yes, the 20 minutes are from when I was logged on earlier.
I've been mostly playing as another character because of the recent exp bonus, so I'm not exactly sure how long the mag has been missing on that character.

Description: The mag that I had equipped for this character is missing.
Comments: The mag was a pink Kama with stats along the line of 15/169/16/0. I checked the banks of my other characters and the common bank and it's not there.
