accidentally hijacked hosea's horse right after a mission ended by jumping to it

[sketty]

replaying the game for the second time, i just finished "The Spines of America" and decided to return to camp with hosea, after he got off his horse i was given the prompt to jump onto his horse and it just worked? i'm unsure if this works anywhere else but the game just let me do it first try.

i note that i was kicked off of it a bit after when i tried to ride to valentine. i saved whilst i was still riding it but that did nothing, maybe there's a way to keep the horse after getting to the point of jumping but i'm not sure of many glitches that could help, it's up for grabs i suppose

The only reason to jump to Silver Dollar is to ride it just outside camp, hitch it to a tree and kill it with dynamite so that you can get the Rolling Block rifle early, even though you get it in Chapter II anyway.
