I am going to reproduce this on experimental tommorow. It works on stable well.
The best combination to reproduce it is to have 3 people in team.
a) With wanted items.
b) With handcuffs and keys.
c) Empty dude.
The guy with items get logout, the b guy handcuffs him and when it's possible c guy takes all items on himself then b guy uses keys on a guy. Guy with items dissapears after 30s and he is able to log in with duppled items.
