I am about to walk into the camp where Salt-Upon-Wounds is when the screen goes black for a cutscene. Then I hear Joshua Graham say "That's it!" while it is still dark, and I am suddenly at the camp, with Joshua Graham hostile towards everyone, including me. Trying to figure out what I did since he left me earlier in the quest that would have turned him hostile. Doesn't matter if I walk into camp with no drawn weapon, he always goes hostile. I'm going to see if I have a save prior to starting the quest. I do not recall shooting any Dead Horse or Sorrow tribals, just White Legs. Anyone else run into this?

I had one bug where Salt Upon Wounds just sat there and wouldn't trigger dialogue but, I just reloaded a save to fix that (which was unfortunately VERY far back)

I must have accidentally shot and/or killed one of the friendly tribals. I reloaded from an auto-save created just after emerging from the Three Marys cavern, and was careful to only shoot White Legs. This time I got the expected cutscene.

That was the only bug I got in the whole DLC ^_^ besides all of the mantises and fire ants (pun)

Worst bug I got was right at the end I got stuck in a canyon wall with a white leg with a sishkebab trying to kill me with no luck.

Had to reload that autosave.

Seems like all the bugs are in the final quest.
