Currently I have my settlement at Level 4, and trying to get it to level 5. When I go to build the grain farm, there is no sign outside to allow me to actually build it. I checked around and can’t seem to find a sign anywhere.
Also not sure if this is meant to be, but the house is already built at the grain farm. I can go inside it and find two notes.
And not sure if this causing the issue, but I have only done the first mission since I arrived in England, as I have been completing side quests and finding collectables. Is the grain farm story locked?
