Rather than sinking the TC, if active bets were to stay, it would stay active. I like this idea, I ping too sometimes during an active bet and nobody gets the TC when that happens. I also cannot see any complications of force pings as it doesn't benefit them or anyone else, whatsoever (the spectators of the match). If it's the players in the match that have a bet and then force ping, they've lost anyway so they won't get their TC either way.
