Jiquani's Machinarium Checkpoint Glitch

Upon unlocking the checkpoint by the door to Jiquani's Sanctum without having socketed a soul core into the door, going to find & defeat Blackjaw, and then teleporting back, I was placed directly in front of the door to the Sanctum, bypassing the need to find a soul core for that door. I tested this several times and found that it happened on repeat attempts!
