The most annoying part of a big game (I guess it is fixed in the expansion) is to conquer a planet and then get stuck with a factory upgrade which applies to every factory in your collection of planets. If you leave it there, it ultimately starts
to bankrupt you. So I have to manually delete them and stick some stock exchanges in there. This can take 45 minutes. Then I get another factory upgrade and have to do the same thing over.
Any way to empty the planet improvement queues in a hurry?
Maybe I should build fewer factories and enhance them myself to get the same production.
