Early in my second playthrough in RDR2, around Chapter 2, I received a tip-off to rob Catfish Jacksons. I chose to rob it at night, and the encounter didn't occur. Although I was disappointed, it made sense, it was night after all. However, when I went inside, although Nate was asleep, Algie was nowhere to be found. Moreover, the money wasn't retrievable from were it normally is; Instead, Nate immediately woke up and proceeded to stab Arthur with a knife. Again, this wasn't out of the ordinary, so I non-lethally hogtied him. However, because I couldn't get the encounter to work, I couldn't get Nate to tell me where the money was, and the game wouldn't let me take it, even though I knew where it was. So I left. To reiterate, I didn't kill anyone.
Cut to Chapter 4, and I go back to Catfish Jacksons to retrieve Strauss' debt. As expected, Algie is lying drunkenly by the river. However, instead of the interaction occurring as expected, Algie yelled "You took my boy from me!' and engages in a fistfight. After knocking him out, the game tells me to retrieve the debt from his house. Also, Nate is missing; I can't find him anywhere.
What's going on? Does the game think I killed Nate?
