This one may be in someone's list already. I've noticed an irritating glitch when I send a fleet of constructors to an existing spaceport. If there are more ships than there are modules to build, the ships remaining after building modules kind of dock or something. All fine, great. Like that. But when a new module becomes available via tech research, and I click on a starbase to build that module, the build button is greyed out. I have to manually move at least one of the constructors from the starbase dock off one hex then back to the base. Suddenly the build button works.
Anyone else seeing this?
