The fact the quest keeps repeating like this means there's something wrong with my game files and it has this quest set up like this. It says 'Started _ The First Step_ Talk to the settlers at Greentop Nursery'. I went back to an old save and got the quest again to show what shows up when it auto accepts. I do not have any other issues with other quests in the game, just this entire questline is bugged, starting with 'The First Step', so now I can't continue with the Minutemen questline, which consists of many quests.

All attempts at talking to Preston Garvey again do not go anywhere. When I talked to them again after the quest finished, they let me ally with their settlement but they did not and do not say anything else after that. I tried going to Tenpines Bluff and talking to the settlers, but they just sent me to Super Duper Mart for their own quest. When I went to Greentop Nursery, a settler there pointed me to go to Dunwich Borers, and all the enemies there are starred enemies, so obviously I wasn't supposed to be there yet. I received the quest from Preston Garvey when the group arrived to Sanctuary, but the quest is pointing me to go to Greentop Nursery (it says in online guides that this quest is supposed to send me to Tenpines Bluff).

I have an issue with one of the first quests in the game.
