Checkpoint Travel Bug in Jiquani's Machinarium

If you use the checkpoint travel to the checkpoint that lead's to Jiquani's Sanctum, you appear on the other side of the stone door, which aside from being exploitable, makes it so if you haven't killed Blackjaw yet, you need to reset the instance to kill him if you collected all soul cores from the zone, because they become stranded on the small hall between the stone door and Jiquani's Sanctum.
