Sentinel Messes Up Cat NPC's

[Gh0stKitty]

My cat NPC's only have Greeting and Greet Range set. Everything seems to work just fine until you restart the server. After it restarts the npc seems to make a second NPC with the basic Black_Cat skin.
If your npc was set to be invincible with /Npc vulnerable It looses that and is able to be damaged/pushed/etc. It also glitches the greeting and sometime it will not show up if the npc is doubled.
