你是不是设置了 拆除那个颜色了 这样很容易就拆掉的
Have you set the color to be removed so that it can be easily removed

nope, i haven't set any grind color, i actually didnt even touch colors, i build all in pale gray :p
i even checked that to make sure, and disabled the grinding on color from all the build and repair blocks and it still didnt help, i also checked the ownership (i played this map alone)... it still kept breaking (and it did not get grinded down, it started burning even, and i have no mobs or anything activated in that savegame)

the only way i could fix this issue was by changing the grind-settings and disabled grinding of repair blocks alltogether, that worked. (ps, in the end i only had 1 builder in the grid, and no ships and nothing, since it was a pretty new game)

since then i havent played that particular save game, and since that moment i set _every_ build and repair system up to NOT grind build and repair systems, to make sure this doesnt happen again, so im not sure where the issue came from.

The weirdest thing is, it happened out of the blue, and the build end repair system kept breaking (being in flames, not just getting grinded down)
