I have always cried every time someone told me they restarted their game because of this glitch.
NO. STOP. READ NOW!
When you have this glitch/bug there is no need for you to quit the game or end it through the task manager. All you have to do is
1. PRESS F5 on your keyboard - This will give you a menu.
2. Select with your keyboard arrow or Click Edit Town or Edit in Town whatever it’s called.
3. The UI bar will be back to normal!
4. Then you can choose to return to game or if you’re building/furnishing a house,click on the house again and edit :)
5. You won’t lose any progress.
You are welcome. If i find any of you quitting your game when this happens,I’m going to kick your ass because I am the one who ends up crying afterwards.
