After 125 levels, apocalypse 5+, an hour spent in the mushroom level with food reserves and refreshment enchantments rank 3, and half an hour at camp just spamming the potions button it still doesn't unlock. 

I want to understand why and just keep reminding you guys that it still isn't fixed. Checked the mcd-2015 ticket page and it says resolved, despite it clearly being just as bugged.
