Here are a couple of pictures of some weird graphics. Notice how the train engine is a twisted 2D/3D mess and the box cars are missing their undercarriage. Buildings are twisted as well, some are bloated and some are missing side walls. I like the free-floating electric lines over the track!
When this first happened, I thought the problem was just with the saved game file, but it wasn't. Somehow, my 1.06V had become corrupted. A fresh install of 1.06V solved the problem. I have to admit. It had me worried for awhile.
