Witcher 3 Script Compilation Errors

[M A J O R]

Just came back to Witcher with the same mod setup I had been using without issues for a long time. I have no idea what mod or missing file these refer to. Was hoping someone 

could shed some light on what these mean/how to fix them. I've run WitcherScriptMerger and found no conflicts from the mods themselves.

The Witcher 3 is really, really picky about mods being compatible with each game update. I'm unsure if this error appears for other reasons, but the only time I've ever seen it is when trying to run the game with an incompatible mod installed. Check for updates on your mods for the latest patch.

 

In particular (but not exclusively), mods that enable the developer console seem to need to be updated for every patch or they will almost always produce an error like that.

I reinstalled them all with the latest updates with no results. I ended up parting with Friendly HUD and one or two other insignificant mods, I can run the game now. Thanks for your insight.
