The Cake network seem to be taking that software bug seriously, although don’t seem to have determined a cause yet (they’ve just upped the monitoring of hands more).
An excellent response from Lee Jones, their representative on 2p2 forums though;
A: If you have a hand history, send it to our support people. If you want to ask our support folks for your most recent 1000 hands or so, feel free. If you can find (and we confirm) a wrongly pushed pot, we’ll ship you $500 for each occurrence. If you were the true winner of the pot and it wasn’t pushed to you, we’ll send you double the size of the pot plus the $500.
Pretty good if you think you can remember it happening. Both Hold’em Manager and PokerTracker validate each hand imported though, so I guess there’s a possibility they may have rejected it and you won’t find it in your database (although it would still be in the original HH). That’s only a guess though, I know they check pot size on each street but checking the appropriate winner might be too much of an overhead for them to bother…
Update: lol, i should have read just a few more posts further 
They’ve found the problem;
The result of all this was for the system to believe that it had a side-pot between the sitting-out player and the small blind (the guy with the kings). It evaluated that pot, awarded that pot to the small blind, and then had no more pots to award, so it ended the hand.
We’ve fixed the code and are testing it. There’s a pretty good chance we could have gone another four years before we saw this again, but obviously we’re not going to wait and find out. The $500 offer I mentioned above stands; we think we’ve got this one beaten.
As regards the people who were involved in the meteor-strike pot, we’re going to treat it like a bad beat jackpot. We’re going to ship $500 to the guy who had the ace of trump and should have won the pot in the first place, $250 to the OP in this thread for reporting it, and spread $250 around the other players who were dealt in, including the mystery player who wasn’t dealt in but managed to fold anyway. Were it not for him, we’d have never found and removed this bug.
Lol, it’s like a bad beat jackpot!!! a huge pot you win you’d be praying that it gets it wrong and ships it to the other player!
Oooh. Thanks for the update; I had stopped keeping up with the 2+2 thread. Interesting glitch; I’m glad they got to the bottom of it.
Lee Jones was on 2+2 podcast, discussed this issue. seems like it was a rare error.
That might be interesting – Lee Jones sounds like a responsible guy, the sort of person you want handling this kind of situation (at least the PR of it, but you’d hope the force behind getting things fixed). I’ll hunt the podcast down and see if he comes across live in the same way he does on the forum…
What are the chances that someone could’ve exploited this bug before they found out about it? Say if you found out about this, you could possibly had some friends play in on the same game and you intentionally fold even if were not dealt in coz you missed the blinds on purpose. A number of you (and friends) are bound to get many wins wrongly.
Seems pretty unlikely – it stemmed from a bug where a joining player sees a fold button when they shouldn’t have, and I’ve never seen this happen.
True that these things can be exploited though – there’s a thread on 2p2 that’s been talking about an old SNG bug where if you lose with automatic replay on and there’s not enough money in your account, then you still get to play.
People were playing $5k sngs and the near empty BR player was chipdumping to the other player. There are graphs showing hundreds of thousands of dollars being taken…
