Paths messed up

Hey, guys! I have a problem (obviously )...
I tried using the world editor to make routes for two cars on Italy map. I closed the menus "wrong" by pressing the arrows and they stopped opening. I found a solution on YouTube - it was View->Layouts->Revert to factory settings. It worked. But after that I noticed that when I spawned in traffic, there were only parked cars and all the moving cars were in the water way offshore. And when I want to set a GPS point, it's a straight line. When I pressed View->Draw Navgraph I think my game froze. I'm kinda impatient, so after 30 seconds of nothing happening I restarted the game. But yeah, I suspect something happened to my paths... Please help! Thanks!

Nevermind! I fixed it! I saw another post suggesting what needs to be done for a similar issue is press Edit->Reload Navgraph and I did it. It worked! Thanks anyway and thank you, random user I forgot the name of!
