Project 1999 - Game Mechanics: lost 1400pp in a trade for no reason

hi,

i have no idea what caused this, but at approx 9:25am PST this morning, i initiated a trade with Philemon with 1400pp for two Diamondine Earrings. i tapped F12 accidentally and somehow the trade got cancelled and my plat disappeared, but he says he didn't cancel. here's the log:

Mouse control deactivated.
The trade has been cancelled.
Philemon has offered you a Diamondine Earring.
Philemon has offered you a Diamondine Earring.
You no longer have a target.
You have cancelled the trade.
Mouse control deactivated. Use the right mouse button.

i did not accept trade, nor did i trade with anyone else. i gave Philemon another 1400pp, but it would be most appreciated if my 1400pp that i lost were refunded since this clearly appears to be a bug. thank you!
