Helper Edit
This appears to be an issue with custom crafting recipes which are loaded into the client when joining specific servers (e. g. Lifeboat) and remain after leaving the server for some reason.
A simple fix/workaround for this is to restart the game.
Crafting with cobblestone does not work, tried crafting stone tools and furnace without avail.

I have joined a lifeboat server previously before this bug occurred. Also, shortly after I posted this bug it appeared when this bug did happen crafting didn't work at all (I'm pretty sure this happened but not 100% sure) unless I closed and reopened the game. Currently I don't know how to recreate this bug it just randomly occurs every couple irl days or so.
