Try taking out the game and cleaning the inside it might be dirty. If this doesn't work then unfortunately your game is corrupted or messed up somehow and you need to get a new one.
Truss bridges are lighter than beam girder bridges. They take up more height but are strong and carry loadd in tension and compression rather than bending.
All true trucks are rear wheel drive or 4 wheel drive. Because of towing and payload needs trucks are rear wheel drive or 4wheel drive. If you have a heavy loadd in the back of the truck and it was front wheel drive you would not get any traction, the same as if you towing a load.
try using a lighter weight oil. Under no load the engine seems to run fine, because it has enough oil on the cylinder walls for no loadd. When load is applied it needs more lubrication, which isn't possible because the oil is cold. Like the consistency of cold syrup. When you warm syrup its easier to spread. Same with oil. try using a lighter weight oil. Under no load the engine seems to run fine, because it has enough oil on the cylinder walls for no loadd.
