So I decided to try out the new alchemy filters and it seems that I'm unable to craft multiples of the exact same mutagen, is anyone else experiencing this?

yeah super patch broken alchemy - glad Ive crafted 2 big mutagens already.
well - so now we have to wait for a patch to a patch.

btw I wanted to try this:
mutagens cant be dropped so I need to sell it to a merchant, craft new one and buy back,
but it can disappear from merchant right after you close trade window

ok just tried it - sold to herbalist all one-type mutagens and you are able to craft them (you can even access alchemy without exiting dialog with herbalists)

aaaand it works, yes its painfull to search for greater mutagens - they all look the same, but you are able to craft it this way....

oh and lesser mutagens and unique mutagens disappear it you sell them to trader, normal mutadens and geater ones stay in traders inventory

found that you can drop mutagens, from inventory screen. well thats easier

Yyep, same problem all over, the drop and craft workaroound works fine, though it's pretty annoying :)

Same shit with White Gull and any other crafting component.
