Apparently there is such a syndrome indeed, I had no idea!

Well, if you bid the max you had, then you did your best.
Maybe someone else with more funds wanted it badly too. I know I've overvalued items when I really wanted them, and bid way more than they would usually sell for.
And in these last auctions I've been outbid by users willing to pay even more than I do!
Anyway I'm hoping we keep getting these auctions from Firn.
If there is a positive reaction (meaning users start to get active in them, and we sell our own items for FPs too) it might re-activate the economy a little bit.
