I was playing Cities XL 2011 and I put down a megastructure. I never started building it. I went to save my city, but I accidentally clicked load, so I am where my city was a while ago. The megastructure isn't on my map, but it says it is on the blueprints and it wont let me put it down. I want to delete it and put another down, but I cant find it. Please help.
