Hello :) This is a wonderful modpack you've built! It's really nice to see some many fish mods all working together like this.
Recently I've worked with the author of the fire place mod to allow fish to be cooked on the campfire that the mod adds. This was done by creating a new "cooking" category that is now used for all the cooked fish recipes.
The cooked fish mod goes through and adds the "cooking" category to all the furnaces, and the fire-place mod adds it to the campfire. It would be great if you can also use the cooking category if either of those mods are enabled so that we can still cook fish on the campfire :)
