Bug in the Trade system ?

Had troubles trading for exotic baskets (between friends). When sending the coins for 1 exo basket, the other player gets a Transaction Failed message when clicking Accept. The exo basket is still in his star menu, but I don't get a mail back with the failed transaction. Also - when I send the trade, coins are subtracted from my coins total and nothing comes back. I basically lost 525 coins this way (3 x 175). Tested and confirmed the bug with different players, also I understand it happened to other players as well. The other way around - sending the exo basket and asking for a resource in exchange - works OK, no issues there. I sent a similar trade - coins for an adventure, and the trade worked OK - it seems only exo baskets are affected (I didn't try with other special items or special buffs).

Anybody else came across this bug ?
