The Ossuary Loading Save Bug

In the Ossuary, after obtaining Lucanis and he pulled the stone slab from the fade to allow the party to cross the chasm, there is a battle with some Venatori and the demons, after which you can loot your first rune of the game. I equipped this rune- then saved while standing in front of the red crystal locked door, and closed the game. 

Later, after loading that very save, I was placed on the side BEFORE Lucanis spawned the stone slab (before crossing the chasm) instead of in front of the door where I had left off (see screenshot); and the battle on the otherside had been reset (also screenshot). I still had the rune, as if the battle had been completed, but the save did not save my physical spot, or the battle status, forcing me to redo the battle. 

In the pictures, you can see me standing before the chasm with my health down, as I didn't heal after the battle before saving. I have the rune equipped, and when walking around, the enemies have been reset. 

I'm playing on PC through Steam. EA ID is Krazylulu822, Steam ID is Krazy Lulu. Reloading the save a second or third time did not fix the issue. Not a game-ending bug, just a kind of annoying, inconvenient one.
