I just made this huge platform - two foundations on top of each other - 30 x 45 arena. Tried to place a greater wheel and it says overlapping? WITH WHAT?
Or it says not enough contact with the ground? Uh, a big huge platform says I have plenty of contact space
I always find myself without the amount needed to build the foundations so I build walls and balance myself to place. I always wonder what observers think when i do stuff like that.
This can happen sometimes depending on your ampleness on the ground is this configuration
Have you tried to mount your wheel down or simply turn it via the options of vertical displacement, inclination and rotation?
otherwise there is as on the Ymir altar a shift that can occur preventing you from centering your object correctly
