Lost roads and building at a large distance. (Cities: Skylines)

Exactly the same problem. Checked the game cache, all is good. Don't know what to do, I think maybe fashion some, if not, it seems to me only to reinstall and transfer the saves, because even on the new map exactly the same problem. Maybe you decided this problem?

Most likely it's due to fashion Real Time. After removing it the problem disappeared.

At the beginning of the game for example only loaded the safe, the road disappears, after a while the bug disappears. That is due to the optimization.
