I keep losing my gearing bonus when the bottom part of the production queue turns from green to orange and red. But when this happens, I can never find a reason for it.
I've always got plenty of IC in production. I'm playing the U.S., so I've got an abundance of energy, metals, and raw materials and lots of manpower. I've looked around, but I just can't find any explanation for this.
Even if I do nothing, it almost always goes back to normal the next day (on very rare occasions, it's taken two days). But that's enough to lose my gearing bonus. (Yes, I try to keep long production lines at the top, but at this point in the game, I've got long production queues everywhere, pretty much.)
OK, it's not a big problem, admittedly. I'm not sure how much the gearing bonus matters, anyway. But I'd still like to know why this keeps happening. Any ideas?
