Jiquani's Machinarium - checkpoint teleport skips past locked door, can soft-lock side content

Hello,

in Jiquani's Machinarium you are supposed to gather cores in order to socket them into Stone Altars and unlock doors. One such door blocks the exit into the next zone, Jiquani's Sanctum. This exit also has a checkpoint, by the altar, before the locked door.

I found that by teleporting to this checkpoint, I was put behind the door, even if I didn't unlock it first.

It's not a big deal on its own, maybe just lets you skip the zone mechanic (gathering soul cores), but I also managed to soft-lock some bonus content for myself this way. Exiting the zone drops any small soul cores in your inventory, which now means they are on the floor in this room locked from the outside and cannot be retrieved. This means I cannot use the soul cores to open the other side rooms without resetting the zone.

Might be relevant:
1) I picked up 4 small cores first.
2) I used 1 core to open the door to Blackjaw and killed him.
3) I then teleported from the Blackjaw checkpoint to the exit checkpoint, which put me behind the locked door.
4) proceeding to Jiquani's Sanctum or town portal leaves the cores locked in this room
