thelostdunmer: Encountered it on a previous install.
Fix (Completely uninstall game and delete The Witcher 3 directory under GOG, save you gamesaves!)
1. Install base game > patch to 1.22 > patch to 1.24 > patch to 1.30.
2. Install DLCs > patch to 1.30.
3. Install Heart of Stone > patch to 1.30.
4. Install Blood and Wine > patch to 1.30.
No errors. Game launches. Geralt kills.
I've been installing in that order, but when I get to the 1.30 patch for the base game it gives me the metadata error anyways. This is a fresh install (after the galaxy 1.30 update broke my game completely). However after closing the patcher and launching the game it tells me its 1.30 anyways. I installed the rest and loaded my old save and it seems to be working fine, who knows.Fix (Completely uninstall game and delete The Witcher 3 directory under GOG, save you gamesaves!)
