it exists a gamebreaking bug your robotics has a limit of 6 tons but a Tier 5 Chassis has a Weight from 6,5-15 tons so they cant finish the car i got stuck wait to get the hotfix Update and download it later i hope the first updates arrive fast or maybe i buy it xD
The Steam version of the game has already been updated to fix this issue. You can now collect all the parts on the robots and leave the body on the mechanics. Happy gaming!
