As soon as I gave the door a pressure plate it started working again. So my workaround to allow for doors to have null references to a trigger volume became this:\r\n\r\n```\r\nif (PressurePlate)\r\n{\r\n\tif (PressurePlate->IsOverlappingActor(ActorThatOpens))\r\n\t{\r\n\t\tOpenDoor();\r\n\t}\r\n}\r\n```"}}
