I think that is one the most hilarious things I've ever seen in my entire life regarding Blockland..
Are you sure it's up to scale? I mean sure you have it done, but it might as well as in-game to be smaller than the wheel. Try making it bigger and see if that solves anything, because you do have a wheel, if the thing is very small and the 4 wheels are close to each-other it might look like that, or try orbing into the wheel and see if you see anything.
