Elden Ring patch came out, looks like it finishes some of the NPC questlines that people couldn't figure out.

* Added a function to record an icon and the name of an NPC on the map when you encounter that NPC.
* Added NPC Jar-Bairn.
* Added new quest phases for the following NPCs: Diallos/ Nepheli Loux/ Kenneth Haight/ Gatekeeper Gostoc.
I haven't touched the game since I beat it. Probably going to finish these questlines if I can and hopefully didn't get too far in the game. I'd be just reloading from before I chose the ending.
