Buildings templates disappeared after i tried to save a castle into a template

Summary:

So one day i was designing a giant castle, but it must have gotten bugged because an error message kept popping up. It didn’t crash the game or anything, so i took no notice and constantly closed the report. However, i soon realized that when i tried to save the castle’s template, it hung the game. I then deleted my castle and proceeded to expand my town, but i realized that all my previous building templates were gone, and when i clicked on building templates, the same error message will pop up. I decided to start a new game to see if the problem was with the old one, but to my dismay my building templates were still gone when i tried to build something. I’m not sure what helps but here is the error message.
