The reason I want this is because I recently got scammed and wasn't even sure what happened until I realized that my ce did not go up, I tried to walk back but couldn't find the person to see if maybe it was even an honest ( though bad ) mix up.
I scrolled through the chat log to find the trade information and did find that I was paid in crowns not in ce, it stated what I had traded but not who with, I vaguely remember the username but it was sort of odd, one of those that perhaps the person was lazy and made up a non-sense word so I couldn't remember enough to back track, I tried re-shouting my offer to attract them back but they never showed.
I still hold out some hope that this was an honest mistake but thing is I have heard of knights doing this on purpose, last minute switching offers and hoping the other knight doesn't notice, or in my case is also slightly dyslexic.
If all else fails I could have filed a complaint if I had the username as I was shouting the offer repeatedly before the trade so I do have proof of what the offer was and not that I was just changing my mind or something.
Couldn't you have scanned back further into the chat log looking for the chat with the player you traded with?
Anyway, I guess this idea would help. +1
Man, I hope that it was just a mistake, I don't like scammers, not one bit :/
