This is fairly odd, since stripped logs, woods and stripped woods were implemented in 1.13.

I was messing around with my world and I used a neat trick that you can enable doLimitedCrafting but then copy the recipe advancement file in your datapack so basically yoftu can craft normal recipes, but not custom ones. But I found out... I tried putting a stripped log in my inventory and it didn't give me the planks recipe. This is nothing but a minor problem eventhough it's pretty annoying if applied to some other items.

(If this is a duplicate, I don't know how it hasn't been fixed yet.)
