Are any of the quests in Fallout 4 time sensitive? Will you fail the Quest if it's not completed in a set amount of time?


Solution 1:

There are two types of quests that I found to be time-sensitive:

  • defense of settlements
  • freeing hostages (as part of Minuteman quests)

I ignored those for a while and got a notification later that the quests failed.

Solution 2:

I just failed a main quest , out of nowhere. only explanation I can find is that I waited for about a whole in-game year.
