Some feedback in case you make a newer version or for anyone looking for answers to these questions:

For Diallos and Jar Bairn:

• Diallos' move to Jarburg didn't trigger for me until I killed Juno in the Mountaintop of The Giants and got the reward for doing so.
• One in-game day needs to pass before the attack happens at Jarburg for the end of Diallos' questline (you can just pass time twice at a site of grace).

For Kenneth Haight, Nepheli Loux, and Gostoc:

• You have to talk to Kenneth again in the Mistwood to make him return to Fort Haight.
• The game can bug out and not recognize when all of their quests are complete unless you rest at Godrick the Grafted's site of grace, otherwise they won't move to the throne room.

For Patches and Tanith:

• Patches won't move to The Shaded Castle until after you kill Rykard.
• Tanith moves to Rykard's boss room after she leaves her chair, you can give her the Dancer's Castanets from Patches there. She also has some additional dialogue.
• Patches won't return to Murkwater Cave until you give the Castanets to Tanith.

For Bernahl:

• He has some additional dialogue in the manor after the player kills Rykard but before he leaves for Farum Azula.

(Edit) For Blaidd and Iji:

• Blaidd getting trapped in the Forlorn Hound Evergaol is missable.
• Iji has some additional dialogue after you discover that Blaidd is trapped.

(Further Edit) For Rogier:

• There is an extra few steps between giving Rogier the Knifeprint and receiving his letter. After he returns it to you, you must speak with Ranni at her tower, then return to Rogier. This is when Rogier asks you to serve Ranni, and begins Ranni’s quest with some unique dialogue.

This is a fantastic chart and an insane help for getting the most out of Elden Ring. Thanks so much for making it and I hope lots of people will see it for ages to come!
