I done Chiyo' quest so from now on i can open the crafting menu anywhere right? But i can only find crafting menu when i talk with Chiyo in her sleeping chamber
There was a bug, which prevented people from getting the new skills. I uploaded a fixed version a little while ago. When you're on windows, you can use the update files to quickly add the fix to your game. Then you should be able to get Chiyo's Alchemist skill as intended.
