Something strange happened a few days ago when playing baldur's gate that has been on my mind for a while, and it recently occurred to me that maybe I should post it. I'm writing this from memory and there's a bit of backstory, though.
On my most recent run, after reaching level 4/4/5 on my fighter/mage/cleric, I took a trip to Larswood to pick up Mr. Spoiler. Unfortunately, I couldn't get him to spawn. I tried some fixes that have been posted and got nothing. Repaired my installation, but nothing was wrong with it. So, I started a new game, CLUA'd my character to level cap (boosting all joinable NPCs to level 6) and took off to see if I could get him. I heard he had interactions with certain NPCs (namely Neera, Dorn (who didn't actually have any interactions that I found), Edwin and Viconia), so I went to pick them up first. Picked up Neera in beregost, picked up Edwin in Nashkel, and to make sure he had no complaints I went and killed Dynaheir. Poor Minsc will wait forever in Nashkel, never knowing her fate. Or so I thought.
I then went for Dorn next. I thought I'd pick him up while travelling to Nashkel mines. He didn't show, so I wandered around a bit, then did some reading and found that I had to talk to him in the Friendly Arm Inn first. Bah!
So I travelled to the Friendly Arm Inn, ran into the-
Minsc- Attacks Flaming Fist Guard
Minsc did 10 damage to Flaming Fist Guard
Wait, what? I never touched him! He's still in Nashkel, waiting for-
Minsc did 15 damage to Flaming Fist Guard
Flaming Fist Guard- Death
Orrr killing a guard I guess. Well, that was intere-
Flaming Fist Guard- Attacks Minsc
Minsc- Attacks Flaming Fist Guard
Minsc did 15 damage to Flaming Fist Guard
Minsc did 11 damage to Flaming Fist Guard
Flaming Fist Guard- Death
Flaming Fist Guard- Attacks Minsc
I didn't stick around to see how it ended. As soon as I talked to Dorn, I travelled out to the Nashkel Mines, and when I left fast travel, the live feed had ended.
So, apparently, your current location and it's sub-locations aren't the only areas tracked in real-time.
