It requires to make 2 Vitriol and I can make only 1 now. After that it says that I already have that made. I hope CDPR will see/saw this. Need that potion for my max difficulty walkthrough now :)

Me have steam version, but most likely doesn't matter in this situation.

Basically all alchemy is affected by this oversight. (mutagens!)

Workaround is to drop the components, craft new ones and pick everything up again.

Yup, same issue here.

On top some glyph's recipes don't work properly. Ex: Igni regular glyph requires 2 lesser. I hvae 8 inventory yet shows as 0 when I try to craft it.

The glyph problem's been around a while, there are at least two "lesser" types of glyph (2% and 5%), only one of them counts for crafting. (Suggestion: remove "lesser" from the 5% glyphs)

When I first noticed the 2 different "lesser" types I thought that it was a typo, and not having the formulas, guessed it would be like the mutegens ( 3 lesser -> normal then, 3 normal -> greater).

Phew, good I'm still playing on 1.03.
