Has this happened to anyone else? I was going to play a two dollar headsup game today and
Went to the table and pressed register. Well the game had filled up and the tables switched and lo and behold im now registered for a 28 dollar headsup instead of the two. Lost it of course. Perfect

The lobby lag has done similar to me on several occasions. Usually I can unregister before it's full since it's a 6-max that I get put into. I can HU being riskier. All you can really do is be vigilant in taking it slow and paying careful attention when registering.

To reduce your risk, you can double click on the tournament to open the lobby page and register from there.
