Thanks Kiji, found it. Her first line (the runaway frogs and cats) only moved on to the dish list if the chat box reported a specific answer, but pressing OK on a plain page never sent that answer, so she just stopped after the text. The OK button now carries on to the seven dishes, and End Chat still ends the conversation. The same mistake was hiding in the Magatia PQ NPCs' multi-page talk, so that's fixed too. The fix is pushed but NOT live yet; it goes out with the next game update. I'll move this to fixed once it's in and someone has cooked a dish.

Update: the fix is now LIVE on play.mapleverse.online (refresh the page to get it). Talk to Witch Malady, pick 'Please make me some Witch food', press OK on her frogs-and-cats line, and the seven dishes should come up. Let me know if you can cook one and I'll close this.

Thanks Kiji! Witch Malady's cauldron is bubbling again and her dishes are confirmed back on the menu. Happy brewing, and watch out for runaway frogs!
