I guess someone should mention that the campfire glitch still works in A12. For those who do not know here is how it works:
1) Put 4 x 15 (60) murky water in the camp fire (actually any amount will work but 60 is the new maximum input for water)
2) Click cook and wait for the murky water to become 60 bottled water in the output slot (when it is done do NOT remove them from the output slot)
3) Get the ingredients for any recipe you wish to glitch, for example, coffee (1 x bottled water and 1 x coffee)
4) Click the recipe name for coffee on the right hand side of the camp fire window and it will insert the ingredients into the camp fire
(note you MUST NOT put the ingredients in manually or it will not work... always left click once on the recipe on the right hand side instead)
5) Click cook (leave the 60 bottles of water in the output slot)
The campfire will cook the input item and change the output items to match. In this case you will end up with 61 coffee. Remove the coffee from the output slot as normal.
Sorry if this was already posted elsewhere.
