Oops, thanks for doubling me up, seeya!

So I plop $10 onto the virtual table for a cash game of Limit Omaha Poker, and in my first hand I win a big pot. I lose a small hand, then win another big hand, then win a small hand. It is then that I notice I have $20 after five minutes of play, which is strange for a 10¢/25¢ game. I double checked, and yes, I had accidentally sat down at a 50¢/$1 table, and the big hands I'd won weren't all that big in comparison. I quickly left the game before my luck spiraled downward.
