So can anyone help?
Can provide more info if needed.

I have the same problem.I think they just have to patch it because all of this happened since the last patch.

I hope so :(

You use a mod called traffic++? If so goto your mods > Traffic ++ > Options > Ghost mode

Since the last update I get this when trying to load my already 40 hours consuming city....
Seems there is a building missing? At least that's what my suggestion is - but I haven't deleted any mods or changed them.
Using the same mods as before.

This does not solve the problem for me.
I forgot to mention that the game does not close when I press the button to quit to desktop/main menu.

Same!!! Game freezes with the animation still running, only option is to close it via taskmanager. Not responding to close it via the X or Alt+F4. Also, exit to menu is not working after having loaded my corrupted savegame :(
Hopefully, this is not permanently.... I already have 97% occupied people, and with 87k total... It was a disaster (although a great one) to create all the special traffic solutions...

[Master_Petrol]

me too, i have this problem since the update of today, i dissabled all of the assets and Mods, still no luck, hope there is a fix

[AwkwardTurtle]

Anyone got a solution to this?

[WhiskeyWerewolf]

Yep, pops up every ten-twenty seconds in-game. Also if I try to exit to Main Menu or Desktop, the game simply crashes. And I can't load assets in the editor.

I had high hopes for this game. Then everything broke.

[dopefish]

I'm now receiving this as well. Tried different maps, disabling mods, etc and nothing works. Not sure why it's just started recently—I'm using 1.0.6b which has been stable for me. Pretty annoyed that the developers are seemingly so stoked about the positive press and the impressive workshop that they're ignoring the base game.

game crashes when i try to close it. obviously something went terribly wrong in this great game. im sure the developers will be on it no time.

I have the problem both with and without Traffic++, I don't think that's it.
