The following post contains spoilers for those who as of yet, did not complete Nuka World.
The issue is the following:
I only completed the Minutemen questline until Preston sent me to help a settlement (Oberland Station), before turning in i started the Nuka World DLC and completed its main storyline.
I had prepared for an instant fight, but upon returning to sanctuary, Preston didn't attack me, and when i aprroached him he was just disappointed and angry.
He is no longer aviable as a follower, i think, and also, the only conversation i can initiate with him is about raiding.
He insists that i should redeem myself by killing the Raiders i helped set up bases, and thats that.
I can't progress any quests, etc, regarding the Minutemen. I'd love to have artillery and The Castle, as well as building better settlements but it doesnt seem like i 'll have the chance.
Can anyone help me with this? Any suggestions?
