War factories cannot keep up with unit production after so many of them are built. Units that take a while to build like apocalypse tanks are okay but cheap units likes Tsivils only every other one to every 3 was built. I couldn't verify if I was still being charged for the unproduced units because I was bringing in lots of ore at that time. I came across it playing as the Russians, 7-8 war factories and an industrial plant and a Stalin's fist. I was able to work around this by designating a new primary building between each unit so that every one of them in the queue could be made. Ever come across this one before?
