MC-264204 Fix
A server-side mod that fixes a bug when the death from a goat is not tracked by advancements and statistics. This issue is tracked here: https://bugs.mojang.com/browse/MC-264204.
Technical description
The damage dealt by the goat has a unique NO_ANGER flag, which hides the attacking entity from the attacked one, thereby preventing mobs from becoming aggressive in response to the attack. However, this flag does not account for cases where the attacked entity is a player. In such cases, it should not function this way, since players are not mobs.
The fix involves skipping the check for this flag when the attacked entity is a player, allowing the player to be aware of the attacking entity, so advancements and statistics triggers will be works.
This hasn't been taken into account since Mojang added the goat, but in Minecraft 1.20 it broke because they did a refactoring and removed the code that was making it work more or less correctly.
