If you’ve been playing Red Dead Redemption II, you may have noticed an issue in the game’s second chapter, where people who should be important to the gang seem to not be available. While initially fans thought this was part of the game’s realistic nature, allowing characters to live their own lives and do their own activities, it seems that it is a bug related to the progression of a quest.

“If you completed the mission ‘Polite Society, Valentine Style’ at the start of Chapter 2, but needed to use the Retry Checkpoint feature, then Sadie, Jack, John, and Abigail will only appear in camp when they have missions for you to complete,” writes Rockstar on the game’s support site. “We are aware of the issue and are currently working on a fix to be included in an upcoming Title Update.”

If you haven’t yet gotten to the point, Rockstar advises doing your best to do the mission in one go, since there is no word on when the title update fixing it may come.

“In order to experience all vignettes and conversations, players must complete the ‘Polite Society, Valentine Style’ mission without using Retry Checkpoint. If the player fails any portion of the mission they should abandon and restart mission, or load a save before the mission failed.”

If you’ve long since passed it, then you might have missed out on a number of key interactions between Arthur and those characters, several of which are praised as the best-written characters in the game.

Hopefully the patch comes sooner rather than later, but if not, the old west was never about taking the easy way out.
