There are lots of recipes that are missing such as boat recipes and other stuff. Could this be fixed? I don't want to modify the jar file to add the recipes manually.

?? Name a single actual recipe you think is missing in TFC itself, that isn't either removed intentionally or by an addon.

Ash boat under TFC:wood/boat/ash

There are many more missing boat recipes

No, they aren't.

You're probably using an addon that removes them, like I said.

I will test it out. Thanks
