No one is at fault, except for me and ... the person who took them but is still me in the end. Yes, I am very salty. if there is a slight chance of getting them back, I will take it. Since it was my bright idea to drop trade them to wash my characters to save time. Nothing went wrong for 99.99% of the time, why would it happen? Take this as a cautionary tale from me... My feelings right now.... Just kidding, is just a game, we all have bad days and everything can still go wrong even if we do everything right.
I give you credit for taking personal responsibility for your actions. Most would play the victim card. Good on you, and because of that I actually hope somebody returns your items.
Ouch I used to do that as well and after getting stressed each time I just stopped Hope you get it back
