I just glitched out Gravewarden to the point all it did was float in place and await death.
I made a clip on my PS4 of when it happened. It did it’s left hand smash, and when it pulled back the hand didn’t change back to it’s sheathed form. All it did after was float in place. (This was all at while it had 3/4’s of its health remaining.)
I figure it was because on 1st playthrough I smacked it and jumped on it a bunch before activating it, but an actual game wouldn’t have this rudimentary issue.
Of course no Legendary was dropped, because Gearbox is more focused on the stupid “tweaks” that make the game less fun to play… fml…
