My sticky piston contraption freezes the game

Just downloaded the latest update 1.5.0.1 and now all my Sticky Piston doors freeze the game. Not sure what component is causing the issue yet. I tried in 3 of my worlds (i have sticky piston doors in each one) and same issue in all of them. The setup is 2 sticky pistons that is triggered by a pressure plate.
In two of the words my world saved right when i was on top of the pressure plate so as soon as i load it, it freezes automatically and i have no way of playing it. It is completely broken.
