Hello,

when trying to start Witcher 3, I get this:

Error [modcdb]game\player\playerwitcher.ws(1484): Cannot override function 'IsEquippedSwordUpgradedWithOil' declared 'final' in class 'CR4Player'.
Error [modcdb]game\gameplay\actions\attackaction.ws(260): Cannot override function 'SetCriticalHit' declared 'final' in class 'W3DamageAction'.

I deactivated EVERY mod and validated the game through Gog Galaxy. I tried to start the game again, without any mods but I still get the same script comp error messages.

What's going on?

Never mind, figured it out.

I manually deleted all the mod folders and then I installed one after the other.

Even Crossbow damage still works, the only mod that doesn't work is Better Minimap
