Glitching through doors

Okay, so today while playing i’ve encountered this bug. It happened in the sewer area, right on start, on the left side there are wooden door that are locked and require a key, and there is a small archer guy on top of a pillar. I was dodging his arrows while walking face first in the locked door, i used dash + attack combo with double daggers and when he hit me with an arrow i passed through the door without getting the key. I was abble to play the rest of the area without unlocking the door behind me until i died. I tried to recreate the bug but I coudnt realy get it the second time. After getting the key and actualy unlocking the door, the area i was in due to a bug was actualy cleared.
