Today I tried to export my CSR47 car and I get the following message.
But there is nothing in the Export folder.
I get the same issues with any other exports.
I've verified the game cache.
Edit: Turns out that Avast had decided to "protect" the Automation folder. Added an exception and it's looking good again.
Unfortunately this means that I'll be able to build and enter shit cars for challenges and then get upset when I don't win.
