Note that this doesn't show up outside of geforce now with the same save as on geforce now.

I've also reported this bug to geforce now.

Sorry, you are all experiencing issues. It seems that GeForce Now has rolled out an update that completely cut off the game from accessing its very own files. That's quite unlucky. We are looking into it.

We have just contacted Nvidia and are awaiting their response.
In the meantime, please don't delete your save files or do anything with your accounts; they are not the root cause.

Thanks so much for your fast response! Will keep all files and await GeoForceNow. Thanks again! @MaFi-Games

Any updates? I'm missing my attempts at perfect ratio

I saw a post on the official GeForce now forums saying that it’s a game
designer issue related to the most recent patch.
