Ran into this error when trying to place a Cottage for Two for construction. It spammed out the error on the screenshot constantly and had to use the task manager to close the game. Clicking the “Ok” button didn’t do anything as it just gave me another. I’m not sure what caused it to happen, it just happened when trying to place another house after I build 3 others and a Dining Hall. I havn’t run into this yet after starting a new game after this happened.
