Needs a new shuffle algorithm

Every other hand is either a straight draw (34568) or a draw of XX3 flop or 4 same suit. I play poker a lot, probably 6/7 thousand hands and never seen one player have a full house and the other 4 of a kind when playing heads up (no one else in the game). The odds of that have to be incredible, but it has happened a couple times out of around 400 hands Ive played on this app.
