The raid protection is giving everyone in range the amount of protection provided while being offline (in my case 100% offline raid protection) including people that are not authed on the tc.

Same here, but not on all servers by the looks of it. My Duo and Solo it seems to work properly (I'm being told) but the Clans server has at least one location where the player trying to raid isn't getting hurt when the turrets shoot at him. If he backs away out of range of the TCs, but the turrets still have him in range, he gets wounded. I haven't had chance to test this myself but I'll get on as soon as I can to try it for myself.

As he says this could be devastating as a player could stand there and drain all the turrets, making it easier to raid when the scrap runs out or the base owner comes back on. @mr01sam

Quick update to this issue. If you open the plugin and replace 

		private object OnEntityTakeDamage( BasePlayer entity, HitInfo info )
		{
			return config.Protection.ProtectPlayers ? ProtectFromDamage(entity, info) : null;
		}

With 

		private object OnEntityTakeDamage( BasePlayer entity, HitInfo info )
		{
			if (entity.CanBuild())
			{
				return config.Protection.ProtectPlayers ? ProtectFromDamage(entity, info) : null;
			}
			return null;
		}

It will fix this issue.

Applied. Fixed. Yaya!  😘

Thanks :)
