Since only zombies can do alchemy and I've unlocked three zombie skins (deathslug, fungus and pinkie patch) can I also do alchemy, or does it only apply to pre-2015 zombies? I get the 'zombies only' error message when I try but I thought I might be able to if I worse one of my skins. I haven't tried that yet, but would it work?

Yeah, you just need to wear one of your skins to have access c: Not sure if it works with the 2015 skins, it should but as far as I know they were never made to be curable with the Bottled Antilovirus so they might not have been added to the alchemist either.

Thank you! :)
