Would be nice to have something that tracks successful launches vs. crashes and errors for a mod with different versions of VS.
So if the game launches successfully, it sends a signal to moddb with the version number and a list of active mods and moddb increments the launch counter for each active mod for that version of VS. When it fails, do the same thing with a fail counter instead.
It would help pin down problematic mods. With a bit more complex setup, you could also find which mods are incompatible with each other.
