I haven't completed a trade. I've done the leveling system 14 times and it has worked, doesn't meanitI can't mess up once.
I just checked and you definitely retired at level 35. I'm not sure if there is any way to prove that you screwed up and retired just a minute or two of playtime prior to leveling up or not, so you might be out of luck I'm afraid. :?(click to show/hide)
