just wondering if i need to keep it around once i have all the upgrades? will they suddenly become unavailable (like the greenhouse)? --- build a man a fire and he will be warm for a day, but set a man on fire and he'll be warm for the rest of his life. Baka wa shinanakya naoranai.
I just posed this question in the "Answers" section. It's good to know that the upgrades won't re-lock but if you demolish their respective facilities will those upgraded options still exist if you rebuild the same facilities somewhere else (when relocating your homebase, for instance)? Or do you have to research them all over again for the new facilities?
