Ok. I have another question about the polar express RTR set. So i have been having problems with 2 of the cars in the set, the lights keep flickering. I know on one of the cars, the little tabs that touch the axles aren’t fully touching, but i don't know how to fix that without drilling the rivets out of the bottom of the truck. The other car has all the tabs touching, but the lights still flicker. Any possible fixes?
