Question

I made a game, i invited 2 different people but with a little margin of time (5min) both joined around the same time, i just completed the trade with a guy, he bought 2 low lvl runes,

now the other guy joins, i write <-- Weekend here, but the guy trades with the other guy from the first trade. both leave, now I ow the 2nd guy, but didnt get the item

I payed the 2nd guy, since a trade i initiated occured, and i dont want trouble, but can i ask now the first guy to give the item i payed for?

the first guy payed 40% of the asking price for the 2nd guy item afterward, so I "only" stand to take 60% loss on a item i didnt get

Best wishes
