My apologies if there was another thread concerning this (tried searching for it)
I got galactic civ 3 free from epic and bought 3 DLC along with it (Revenge of the Snathi,Mercernaries and intrigue) all worked well for 5 hours. I saved the game and came back to it an hour later and it kept saying the DLC are not installed.
I tried reinstalling the game,the DLC, even tried the verify option,tried changing folder nameetc etc and reinstalled the epic launcher just in case just incase and nothing works.
