Been having a problem for a while now, Preston Garvey won't stop following me.
When I pick the dismiss option he says "ok babe, see you at home" but doesn't leave and the option to pick which settlement to send him to doesn't appear.
I've successfully completed all the Castle related quests some time ago and didn't have him follow me as a companion until a while after.
I've turned all my mods off and nothing changes, I have no quests related to him apart from the standard another settlement needs our help, and when I hand one in to him he immediately gives me another.
Anyone have any ideas?
