Passive mobs drop cooked meat (caused by outdated/invalid data pack)

Cannot reproduce unless they are killed with fire / lava.

I just started a brand new world and was about to report this bug myself. I crit a sheep in one hit with a wooden axe, thought maybe it was a new mechanic for crits? So I tried normal attacks, multiple hits with an axe, sheep dropped cooked mutton, made a wooden sword, sheep dropped cooked mutton. I can confirm that I have had this issue as well.

[Edit:just went and found a cow, it dropped the cooked variant as well for me

I think I may have found something relevant? To b sure this was a game issue I made a copy of the offending save and opened it clean, animals dropped raw meats. Then I loaded my data packs until the problem occurred again. OP were you by any chance using the more mob heads data pack from Xisumavoid's site? If I had to guess, that's having issues with the snapshot. Not the snapshot itself.

Thank you for your report!

We are getting cooked meat using unenchanted swords on our server. We are using some of Xisumavoid's data packs and a few custom, but nothing that should touch mob drops.

A recent crash is enclosed unrelated to the "cooked meat" issue. Let me know if you want me to force a crash or send a copy of any "interesting" data packs.

This is caused by an outdated loot table with a faulty condition for the furnace smelting. Please contact the data pack creator and ask them to update their pack.
1.13:

"condition": "entity_properties",
"entity": "this",
"properties": {
    "on_fire": true
}

1.14:

"condition": "minecraft:entity_properties",
"entity": "this",
"predicate": {
  "flags": {
    "is_on_fire": true
  }
}

They are 1.13 "dedicated" packs. I'll search for this and update privately, then watch for the 1.14 Hermitcraft Vanilla Tweaks update. 🙂 Thank you! I'd never have come up with that one.

For those who are using Xisumavoid's data packs mainly more mob heads v1.2.0 that is the issue more  likely
