If you're seeing a glitch in the Structures 2.0 competition where the truck on the left does not move and the truck on the right veers off to the right of the ramp, this is due to a bug in the 32-bit version of Google Chrome. The bug has been fixed in Chrome version 62, which was released on October 18th, 2017. Please update Chrome to correct the problem. Alternatively you can use another browser such as Mozilla Firefox.
