Hey,
I've run into a very odd issue with my settlements.
Thanks to having Preston Garvey as a companion for a long time, talking about nothing but "I've heard from another settlement that needs our help"..., I've unlocked nearly every settlement in the game and started expanding every one of them. Some of them I wanted to become trading posts, that specialize in keeping the trade alive throughout the Commonwealth and don't really produce any goods themselves. Therefore I wanted to add several shops (armor, clothing, weapons, medical etc.) to each of those posts, but now that I have build around 20 of those shops I suddenly can not build any shop. I definetely have the ressources required yet I can not build any shop.
What could be the problem, and is there maybe a hard limit as to how many shops you can have in total (for whatever reason... I mean, currently I only make 500+ caps a day...but that's not the point)?
