Ok I tried searching the forums but could not find anything that looked related to this. I'm pretty far into a large game, and I noticed that one of my planets I colonized earlier had a ton of empty tiles. So I inspected it, and it only had two structures built, while everything else in the queue said 'Never'.
Now I can't figure out why nothing is building on this planet. It has a PQ of 16, a maxed population of 6b, 100% approval, more income than expenses, and an enhanced factory. Still, it shows zero social and military production. I don't understand what I'm missing, does anyone know why something like this would happen?
