Looks like a classic mod cache issue.

Please delete the folder ".pdxsdk"in C:\Users\%USERNAME%\AppData\LocalLow\Colossal Order\Cities Skylines II\.cache\mods, Delete the folder playsets_metadata and the file PlaySetSettings .





If that doesn't help we'll need to do a full clean reinstall.





Good luck!

It will be there, but To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

If you need more help start your own thread please.

Did deleting the mod cache get past your original issue, now you have a new one, is that right?

Let's see a new player.log please.
