Some dude and I lost my hardcore character during the keener cutscene. We opened the door after he went to his dying spot on the footbridge.
As you can see in the clip, there is one sitting on the ground and a second keener, which shoots at us. Yea, we lost both characters.
This can be reproduced every time by opening the door too early.
The guy in the clip uses ALT+F4 trying to log out as fast as possible to survive, but as he relogs you can see his character is already gone.
My character died right after the cutscene. You walk out of the door in "Haven" and die immediately. Pretty unfortunate, wasting a lot of time like this.
