Hey Shiva, thanks for the error report!
This happened in multiplayer while the client made streets, right?
We are looking into this on Monday 
No, in singleplayer i play solo
I just tried again and the error didn’t occur.
Please feel free to ask me for information or tests if you want to know more.
Alright, thanks. I think we have enough information for now, will check it out.
Let us know if it happens again!
This should be fixed now, with Apha 3.0.8 actually.
