First time out of the vault

I'm playing vanilla Fallout 1 for the first time (first with any of the Fallout games, actually--figured I'd better start here and get the old-fashioned graphics and godawful gameplay mechanics done with first), and as far as I can tell, I'm experiencing a glitch with the "Guarding the caravans" repeatable quest. I signed up with the Far Go caravan driver; I waited until the right date; I talked to him again and said I was ready to go, and I was warped to a piece of desert with a couple wagons and brahmin with no one else around. I waited a bit and nobody showed up, so I went to the exit grid, which took me to a spot that looked essentially the same, except with three caravaners and a party of attacking raiders. Well, okay, I figured I'd done something right, so after about a million reloads to keep Dogmeat from dying, I finally got all the raiders wiped out and hit the next exit grid, assuming that's what I was supposed to do...and I got a dialog of the caravan driver yelling at me for abandoning the caravan. The Fallout wiki told me that would happen if you use the exit grid when there are still hostiles on the map, so I reloaded and waited a while, thinking maybe it just...needed to trigger or something. Nothing. The two brahmin had showed up as red during the battle (I've got the Friendly Foe perk, but of course even innocent bystanders get the red outline, so that doesn't mean much), so I thought maybe the game was incorrectly identifying them as hostiles and that's why we were stuck. Killed both brahmin. The caravaners didn't protest; in fact they pitched in. And...still no change. They stood around doing nothing, and if I took an exit grid, I got the same dialog about abandoning the caravan.
Am I doing something wrong, or does this sound like a glitch? The former is entirely possible, considering how unintuitive 99% of the gameplay is for Fallout 1, although hitting up Google for stuff like "how to guard fallout 1 caravan" didn't get me anywhere. And if it sounds like a glitch, any ideas on what I can do about it?
