Players able to kill NPCs easily while crouched
when making any NPC melee or ranged, happens harder via melee, the npc will stop attacking players if they are close to them at lower elevation, such as being on a downhill slope or just straight up crouching and shooting upwards at box head, the npc line of sight is straight and cannot see player, forcing it to not attack player as long as the player is crouching within very close proximity. 

Any and all admins looking to create combat npc for Pve content will NOT be able to create boss npcs who drop loot as any player can figure out they can crouch 1 foot next to the boss and kill it over and over without ever taking a single shot or hit of damage at all. When you are not crouching or at even elevation the npc attacks will work fine. But literally all anyone has to do to beat any npc you ever create using this plugin is crouch. Not functional combat. 
i Messed around with every possible combination of settings and yes, accurately no matter what you set anything the npc will never deal any damage whatsoever to any player crouching directly next to it. Naked players can kill your strongest npcs with a rock while staying at full health.
Please let me know if this update fixed the issue for you.

Also if you could post the config your using for the ranged npc so i could take a look at it.
