For the record, I have never used or even installed mods. I was playing two days ago just fine. I barely used the computer between then and yesterday, except that I downloaded the new Toolkit from Steam. Now when I launch, I get data mismatch warning.
I'd rather not "don't show this message" but is it unavoidable? I haven't even launched the Toolkit, so the only files present are what's downloaded. I find it weird that the launcher isn't okay with them. The game runs fine, but I might just uninstall it until I want to use it if it's going to be a nuisance.
