I took the truck into Olympus cave on sandbox mode to collect uranium. I put 5 rocks into the back of the truck. When I go to get into the truck it tells me "There's something in the tipper preventing movement" but it doesn't give me the option to fix whatever it is. I've tried adding more rocks so it tells me it's to heavy and to remove one but that doesn't work. I tried saving the game and rebooting hoping it would fix it, no luck.
