Can you PM me any details, we can look into some logs to see what's going on! Specifics like whether you are attempting this wager in the Live Soccer, or are you doing this in Pre-Live, as well as the bet and the amount will be helpful so we can attempt to reproduce.
Regarding if this is a recurring theme - we've accepted over 20,854+ btc in bets over the last 18 months - so I'd venture to say it's an edge chase that needs further investigation.
PM'd. Thanks for checking it out. Unfortunately for me, the best just won too. It was around half time of a soccer match, which I assume is Live Soccer.
