I can upgrade the buildings in my Korvax settlement fine, but the button to do so doesn’t appear on any building in my autophage settlement. I tried waiting for a bugfix update because they usually do it daily after an update, but none so far. 😟 Edit: It’s sorted now. Details in replies.
On one of my other saves my autophage settlement is stuck at 37:37 waiting for an event. No overseer terminal built yet. I think I need to abandon it and start again.
