So I was doing kingdom of shadow on my barb and on about my 9th attempt I managed to kill him, the catch?
This:
I then went back with a temporary set of gear to try and grab my loot only to die and have all my items bug out (only gave back shitty Double MO'd equip when exiting & rejoining).

EDIT: I remember making a backup yesterday of my char so not all is lost! After the backup however I did find things such as black void and SU labrys (which double MO'd!) and some other goodies that I MAY have been wearing (R.I.P my first SOTNK :c)
