Ive recent lost an item because it got mixed up with Strongest Gear. Having a hard time tring to get it back. What I suggest is that you place a "GLOW" or some other such thing around ALL STRONGEST GEAR Icons... You should be able to see at a glance Strongest Gear vs ANY other gear....
Yeah im usually VERY careful. Only replaced 1 items in 8 years... I Had a lag spike, Im guessing and it didnt swap out strongest gear for mine. Didnt notice I vendered it till it was too late. So fix this, or make items "lockable" so they can not be sold/Destroyed...
