!!!!Party Poker bug lets money disappear!!!!
There is a bug at partypoker/WPT Poker about auto-reloading which sometimes leads to missing money. Some players realized this and contacted the support which confirmed the problem. They don't seem to think that it is necessary to inform the players though. Mostly small amounts, but one guy had 4k$ missing. Apparently this problem usually took place after some popup error. Players who wrote the support got their money back and I don't want to know how many people didn't even realize missing a few hundred $.

So be careful!! And always check account balance before and after play and compare it to Holdem Manager. The safest way probably is not to play there at all right now.
