Game has been pretty good and I haven't noticed any major bugs so far, except for this one:

I came back to the campfire with the stuff for the quest, and Sunny Smiles isn't there. I was able to make the healing powder on my own, but that doesn't fufill the quest. Where is she?

Earlier on, I had noticed, there was a odd little routing bug where her dog just stopped and waited in one area while she went to finish off one of the last Geckos. Not sure if that has anything to do with it, thought I should mention it.

This belongs in the cheats, hints, spoilers section. You'll get better responses there.

Yeah, I will/did. I just thought it might belong in here in case this is the result of some sort of bug (like maybe she's disappeared or the AI had her run over a cliff or something).
