Check the Cameras
There was quite a crowd gathering around the Blue section of the Amazon Room where due to the floor being called after the dealer apparently dropped the deck during a hand. The floorstaff were keen to not divulge any information, but said they were viewing video footage to ensure the dealer acted properly.
Ten minutes later, the footage had been reviewed and the dealer was deemed to have acted properly so the hand stood. Unfortunately, that meant JJ Liu who put in the complaint was eliminated because here 
was no good against 
on a 
board.

The dealer told us she thought she had dealt the river but was actually on the turn where Liu was all in and had been called. The dealer had put the rest of the deck onto the felt and asked the players to turn over their hands before realizing the river had not been dealt. The dealer than retrieved the burn card and river card from the deck, but it failed to alter anything.
Liu argued the hand should have been dead, but only complained after she was eliminated.
