Fallout 1 endings

[plaidchuck]

Hello all a long time lurker here but finally decided to post to ask a question. Are the endings based on the date when you finish the game or do they only activate if you go to a map where the mutant invasion has started?

For example I finished the game and got the invasion ending for necropolis, although I fixed the water pump and finished the chip quest in under 60 days, never returning to necropolis. After that I finished the glow, wandered to find some special encounters, got the bos operations etc, ultimately finishing the game in july. Shouldn't I have also gotten the invasion endings for the hub and the followers?

 

[Per]

The invasion endings are triggered on entering the respective maps (when they are scheduled to have been invaded).

Weird, because like I said I never reentered the necro map again and still got the ending. Come to think of it I killed the mutants at the watershed but the quest was never crossed out and I never got anything from Set, probably has something to do with it. Dunno if that is just something that happens in the game or maybe with the fixit mod.
