Just finished up my TMNT for my 6yr olds birthday party tomorrow and it looks great!! BUT I have adjusted the leaf switches several times and they play game me for a few minutes then they move and lose contact and need to be readjusted again. My son and I played through the entire game and we had to stop 5-6 times to bend the leafs back so they make contact. I plan to order new gromits and new leafs but is there any way to temporarily fix the issue? I can't see standing next to the machine for his entire bday party tomorrow adjusting them so kids can play.
