[2023] mods won't enable

We're seeing reports of this happening but having trouble reproducing the issue reliably enough to investigate it properly. But I just wanted to let you know we are trying to get to the bottom of this.

Mods being deactivated or showing as 0/0 mods is a result of the userGameState.cgs being corrupted and deleted so a new one is created. Restarting the game after it initially happens should let you reactivate your mods. I recommend you back up your userGameState.cgs before shutting down the game (the corruption either happens once the game is shut down or when it's starting). That way you can replace the userGameState.cgs if it gets corrupted again.

The userGameState.cgs can be found here:
C:\Users\%username%\AppData\Local\Colossal Order\Cities_Skylines

This file gets deleted every time I launch CS. I have a renamed backup but if I give it the original name it gets deleted on starting CS. How can I "reload" this file after launch?

Hmm, so your backup is removed each time? In that case we could really use that backup file to see if it triggers a reset of the file consistently. Please make a report on our support forum and attach your backup file there.
