what if Partypoker mucks your hand?

[SNOWBALL138]

Everyone checks to me on the river, and I was about to bet my hand when "establishing connection" came up on my screen. Several seconds later, I'm reconnected just in time to see my hand folded. I don't understand why partypoker didn't just check behind for me or use one of my disconnect protections. No one bet at me, and I was last to act.
Needless to say I had the winning hand, but villain was able to take down the pot with 2nd pair...

Is this fair?
