How to get turrets to shoot RaidableBases NPCs?

Has anyone figured it out? They seem to shoot at everything besides the RaidableBases bases npcs

Here are the possible reasons the NPCs are not being targeted.

(1) You have disabled targeting in this plugin's config.
(2) The target is inside a safe zone.
(3) Another plugin is blocking the turret from targeting the NPC.

My guess is that (3) is the cause here.
