The 0/0/0 center is what happens when the construction process fails, and you're left with a useless building you need to tear down. Usually this only happens when you select a specific type of center to build, or if you already have many RCs in a region.
...If all the lords in OW are trying for specific types of centers, that's probably why they're having horrible luck. As I recall it lowers the chances both of getting a usable center *and* the average quality of the result.
