Alhambra lost!

The Alhambra building I once owned is gone. I don't know why. It's not in the inventory either. It's lost. The only possibility that comes to mind is that I used it in a design, but I couldn't submit it to the competition. More of my buildings might be lost too. I don't know. The buildings always rotate, but this time it doesn't seem to have rotated. Please, I want my buildings back.

thanks

Honestly, I don't think they read the forums. Are there any others here who have experienced a similar problem before?
