Can anyone get mechanics to repair vandalized objects? Mine soddenly refuse. I have multiple mechanics in proper work zones and their only responsibility is to repair the objects but no objects are ever repaired. They are fully trained and have staff buildings available. I even drop them right in front of broken objects and they just continue to "wander." It's a frustrating thing as I have to scan through my entire zoo quite often to fix broken objects. Has anyone else run into this? Any way to fix it?
