Febilian updated Craftable Smashables with a new update entry: Forgot some jars. Read the rest of this update entry...
That would require either modifying all of the smashables at the base level to not be broken, which would affect ALL smashables in the game(including ones from adventuring and whatnot), or re-creating every single one as a new object. I'm not really keen on doing either, sorry.
