Steps on how to reproduce issue:

There’s been new off limit areas implemented could be result of this.

and if you didnt have foundations under them as well they shall decay

I lost a wheel also. I’m betting it was not on a base. I have since went back and redone 3 bases with similar possibilities. Going to see if they disappear now or not. How does one know what an off limit spot is? Shoudl they just not be able to build there??
