Fix real player objects identified as fake (NPCs) when they have disconnected.

Fix fake players (kept online players) not automatically disconnecting after death

Fix fake player death not tracked as a combat log

Fix punish features (e.g. punish commands) not running on fake players

Add untagging when the enemy disconnects. Previously if setup to do nothing when an enemy combat logs, you would remain in combat. After this feature was introduced, if the enemy logged back in while their NPC was spawned, you would be untagged; this was fixed.
