This was happen last night during raid hours. I don’t think they can do all doors at will, but they certainly were opening doors they should not have been able too. It was not our thralls as they all died the previous night. This is happening on an official PVP server, Playstation platform.
While on the subject of doors, is there a hidden setting somewhere so that newly placed doors are ‘locked’ to thralls? This is ultra annoying, having to risk death just to ‘lock’ a door.
One possible explanation for this, and it is purely speculative, is that a lost zombie was responsible for opening some doors. We still had a few zombies lost somewhere in the compound. Most of the doors were ‘locked’ to thralls, but not all of them as some were replaced during the course of battle. So one of these lost zombies, who are lost behind locked doors, walls or even foundations are still within range of an unlocked door. Even though they cannot physically get to this door, they are still able to open this door.
For example, there is a hallway with five doors. Doors 1 & 2 are locked, door 3 is unlocked and doors 4 & 5 are locked. A zombie (or thrall) nearby wants to go down this hallway but cannot because doors 1 & 2 are locked, but since door 3 is unlocked, he goes ahead and opens it. Does him no good though, since he cannot get through the first two doors.
