Has this always been the case for you? Or only since when?

Is this on vanilla maps, or ones you've edited?


Please gather both these two informational files, and attach them here:

DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

I got a new Computer recently.
The Problem started when I was first playing on a newly installed Win 10. In the beginning I was running the Ubuntu 20.04 Installation I moved from the old pc, on which the game (and OS) is running fine with the new hardware. Which was quite surprising.
The map is Vava'u island. It should only contain vanilla content.

Just to be clear: the problem did not happen under Ubuntu, but does under Windows 10, on the same machine? Is that right?

This save game appears to be corrupted:

'nova_vavau_prog' failed to load.
System.IO.InvalidDataException: Unknown type to deserialize

And there are many mods and assets in use there.


Let's try it with clean installation: In your Steam Library right-click on this game and choose Properties. Click on Set Launch Options, and paste this in there:

-noWorkshop -disableMods

Then start a new test city - do you get the same problem then?

Googling that AMD driver version - it's from 2015, can that be right?

If so please uninstall it with this tool:

https://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx

Reboot, then install the latest from here:

http://support.amd.com/en-us/download

then reboot again.

Good luck with that!

Hello AndrewT,
this actually solved the problem. Thank you.
Although I am confused since I am shure that I have installed the driver you recommended.
In the meantime I removed the AMD Radeon HD5450, which I used for my second monitor.
Maybe the problem was caused by installing the older (most recent actually from 2015) driver for this card, after the driver for my Radeon R9 380.
Also the driver for the HD5450 itself could have been the cause of the problem, since it should have been removed by the clen-uninstall-utility program.
