Hello,
so im bumbling around with alchemy and with Mushroom Decoction there seems to be a weird bug and not all ingredients are accepted at first.
I did the following: Mineral calcination (Diorite + Slag), Herbal Grind (Bloodstern +Lingonberries) then i tried to grab an oyster mushroom and do a herbal decotion. Using an equipped alchemist table and with the oyster mushroom added to the inventory, some of the other ingredients are not highlightes as green anymore and the mushroom is instead (A). Yet, i get the error "you dont have all the ingredients", even though everything is there. Without oyster mushroom the mineral calcination and herbal grind are accepted (highlighted as green) again (B in pic).
If i put everything into a cupboard, all ingredients get accepted (C). If i move it to the inventory all ingredients are accepted and i can perform the mushroom decoction at the alchemy table to an elixier as expected.
I repeated this with other recipes such 2 herbal grinds and an oyster mushroom or different mushroom and i saw the same issue and workaround.
