Rover wheel clipping
My and my friend recently built a large grid cargo rover, plus a pad to park it on. 8 wheels, of the 5×5 size. Originally the pad was single-layer light armor blocks, but after the rover clipped through it the first time, we assumed the rover was just too heavy for the light armor blocks, so the pad has been rebuilt with double layered heavy armor blocks, and I have just returned from an ice mining trip, to find that the same clipping issue is occurring. It does not do it when the rover is nearby while the pad is being built, it only does it when the rover has been away from base and the pad unloads. Something about the pad reloading is causing the clipping, I don't know if that will help track down the issue.
