Mod Organizer 2 gets a way to catch missing files before a modlist install fails

A modlist can be beautifully organized and still fail because one required download has disappeared. Mod Availability Validator gives Mod Organizer 2 authors a way to spot that problem before users run into it. The plugin checks Nexus file identities and other download URLs for missing, hidden or unavailable dependencies, then exports a report for review.

It supports MO2 2.5 and newer and checks both downloads and installed mods. Availability isn't the same as file integrity, and the tool can't restore something that's genuinely gone. But catching a broken link before a modlist goes public is a practical improvement for creators and their users.
