First boss in sewers

I was wondering if the first boss in the sewers has been fixed, and if so, will the door be opened after we glitched through? You cannot progress early in the dungeon unless you know to roll through the door. You cannot get the key to open the door in order to obtain the lever to progress across the bridge later by the whisper. The boss does not spawn. Thank you! Or maybe we’re all incorrect and you purposely did that to make us aware of other mechanics :joy:
