Sorry I couldn't get a screenshot, it was my first run on the demo and it booted me out of my save upon finishing it. Basically what happened:
- Had dirt roads, I believe in a T shape.
- Went to upgrade to stone roads by building over top of them.
- Realised I needed stone slabs for other buildings so cancelled the stone road.
- Upon doing so the dirt road did not properly create the correct graphics to link up the various dirt road tiles. Basically it used a sprite for a straight road when it should have used a T section (or it may have been a bend on a corner, hard to remember sorry)
