With the 3.5.0 update, for whatever reason the progress at the Castle was reset, it says level N/A and Preston is no longer leader. There are still the plots from before but when I assign Preston as leader it scraps them and rebuilds them fresh. This only occurred after a period of time when the supplies, and city plan would not activate on the desk that was there previously. I exited the game and re-entered several times and then it gave me access to the city plan and supplies again but all progress in the city plan was gone, also my sim settlement mods that provide more mayors/ leaders no longer appear to work with this update as they didn't appear as options for the leader. I'm not sure if this is a bug or the update removed the progress in the city but I'm not sure what to do.
