Players hit when they die. This has been an issue for quite some time. When a player dies the death animation and the punch animation play.

The reason that this has not been fixed is likely because it is quite trivial. It has been very inconvenient for me personally because my addons frequently use animation controllers that query attack-time. The animation controller runs the animation despite that a player is not voluntarily attacking.

This is a problem on normal worlds as well as BDS.
