Gotcha. I didn't miss it, anyway. I've seen enough chapter changes in BG1 that I pretty much just hit 'done' right away.
Usually, there's the chapter screen that has the ominous voice of the narrator telling you that help doesn't come cheap in the city of coin. Since both versions of that "text screen" mention either the Shadow Thieves or Bodhi, I couldn't use it.
Absence makes the mind grow fonder, doesn't it? Or something like that.
Alternatives might have come out relatively recently, but I started it ages ago, before I really knew what I was doing with cutscenes or chapter screens, and Aster's route was the one I did first. I felt that a silent chapter change was better than one that didn't work. By the time I got to the part where you leave for Spellhold, I had figured out how to do chapter changes with text screens, but I forgot to go back and change the chapter 3 transition.
Actually, the conversation was easy to remember; I just said I'd come back with the money, and when I did, I was asked if I'd met Harold. There was no intermediate step. I don't mind keeping the money, mind you; I was hoping there would be some XP involved.
I'm still trying to figure out what happened in your game. You wouldn't remember the exact conversation you had, so I'm going to have to follow every possible dialogue path to find out where the problems are. I'll get it sorted out, but it may take a while. I don't have anywhere near the modding time that I used to have. In the meantime, you should be OK with your current game. Sorry you didn't get the explanation.
I restart so many times it's a wonder I ever finished the first game. I've never gotten to Chapter 3 in this game even. I often say, 'hey, let's try such-and-such a character and see what happens when we pick up this NPC instead of that one...' And I never get anywhere. I wouldn't know Bodhi if she bit me on the neck.
Since I'm going to have to redo most of Aster's dialogue, the next version will only work before Valen and Brus spawn for the first time. With that in mind, it's probably going to be much better for you to continue your current game than backtrack. With all the quests and whatnot in chapters 2 and 3, you won't want to be repeating that.
