So, I do the quest to access to the workbench, I set up a planner table, assign a settler because I don't have any unique options according to the planner's desk. After which it asks for the cost in ASAMs then it go to the little cut scene bit where I am floating over the settlement, and then that's it. It doesn't go any further, just keeps repeating the flight and music, the settlers are running around during the day but nothing is built. I tried this a couple of times, and still nothing. I tried dropping out of the cut scene with my pipboy, and you guessed it, nothing is built. no amount of time seems to help either.
