Yeah I noticed that too.I thought it was just me until I looked here.
A few days ago one of my trades said it was accepted but I never got my Strawberry PB, but I did loose about 90k, *sigh* I knew it was too good to be true. But it gets worse. I had 40k out the next day and another one of my trade results came back, this time it wasn't accepted. So I got my NP back from that trade but my 40K I had out was gone.
