I started up a new survival world, and managed to get my hands on a stone sword, and went out to kill some sheep. Once I killed one, it dropped 1 wool, as usual, but 2 cooked mutton. I tried it over and over again, and it repeated.

I'm pretty sure datapacks from that site are for 1.13-1.13.2.
It's possible that they tamper with the "smelting" function in the snapshots.
In short, this is probably Invalid.
Cannot reproduce. Do you have any datapacks installed?
