I have a kitchen setup with 4 pieces, the crafting counter, a storage counter, a corner counter, an oven, with bakeware and pot inside, using mini coal(Actually Additions)to cook, and a tool rack above. When I click on the recipe to cook Raw Calamari it gives me a stack of 64 every time I click on it.

Here is a screenshot of my setup:

Here are the versions I have:
Minecraft 1.12.2
Forge 12.23.4.2759
Cooking for Blockheads 6.4.61
Pam's HarvestCraft 1.12a
Actually Additions 1.12.2-r140

A quick update, it seems to be happening with all Pam's fish to some degree. It is also happening with Minecraft raw fish. With no coal of any kind in the stove.

You need to update to the latest CfB
See #332 and #325

Thanks! 👍
