Yes. Because then, the leaving and stuff is handled by EET itself (via K#TELBGT), which is also where mod NPCs with an EET transition will have added their own handling of the transition etcpp; the ones who don't will leave anyhow because EET took care of that (via the !"None" script blocks).
Yes, there is also a container in bd6100 (EET) that takes all items for detection of import later etc.
Ah, now I get it. The cutscene does not run, EndlessBG1 jumps past it.
Reason again: I tried to make it work in a useful way. But: the SoD kidnapping scene happens after everyone left the party and I&J&K&M&D rejoined. Or not, if there is multiplayer characters. I tried to have it in, it makes a lot of sense, but I either didn't get it to run or NPCs were under some weird spell afterwards, had a purple circle, or whatever. So I decided that the video sequence is enough to let the player know what happened.
