For me, I've tried crafting levels 0 - 3, and with new games created post-patch as well as from loading saved games that were created prior to the patch. When the game was made doesn't seem to matter, although crafting levels definitely have an impact (but not in the expected way).
I was mainly asking the person who said they worked. I tried on two different computers with the same results. I've removed my old save and started fresh with the same results. Even verifying cache, which was fine anyways, had no effect. Some things are craftable at level 0 but not at higher levels. But I was told it was off to the devs to be looked at so we shall see what happens.
