is there a limit to how many oil pumps you can place or something? I only have six others. I can't get these things to build. I have plenty of construction parts and trucks sitting idle waiting for jobs. They build other things but they won't build oil pumps anymore. I even tried moving it around, setting it to urgent priority, and manually moving trucks to ensure the location was reachable, all to no avail. definitely not in planning mode/paused either.
