Updated and tried 2.0.19

Saws cannot be used in a crafting table anymore to cut logs into planks, logs into sticks, or planks into sticks

the strange part is that at least for saw + log its showing a plank output if looking in JEI

But only for Fir Wood, the custom wood in Traverse.

this is with both these options set to true:

B:enableAdvancedRecipeReplacement=true
B:replaceLogRecipes=true

I also removed all my own recipes for the saw in my crafttweaker to test, so shouldnt be any sort of conflict there

It's working fine for me. Are you removing log -> plank recipes via craft tweaker perhaps? Or removing the recipes (as you said you were before)? Or removing / changing ore dict names for the saw?

My apologies, you're correct, I forgot to remove the line where i removed all wood recipes to add my own. It's working now.
