# Description Thanks to Router for pointing out we can actually reuse code that is apparently just always running exclusively on player characters. So it turns out that this game actually has a system for tracking who the killer is. We can skip enumeration outright if the killer was the one who downed the player. There's still BETTER ways to do this, like subscribing to KillReportedEvent instead of MobStateChanged, but I'm a bit too zonked out to pursue that right now. (cherry picked from commit f325d2e78cfb2a2c09466c3e08a8a818cfd6dfbb)
