Hi, I have seen in another post that someone had a double Malficus spawning... has the reason for that been found or eliminated?
I had the same problem, Malficus spawned twice (at his first appearance already, where I refused him. Both of him, actually, just to be sure).
Then I met a double Aster, too.
Also, the dialogue line with Quallo where you ask about the blood (the one that appears in the original game, too, where you ask about the order of the items and his reply is just to turn away sadly) appeared twice. Although the friendly option to get the blood worked just fine.
I'm playing BG2:EE on Windows, and my only other mod was Berelinde's Keldorn Romance, which is supposed to be compatible (but maybe I installed them in the wrong order?).
I wiped them and did a clean install, because the PID in Keldorn Romance was totally messed up, too. Will try again and then post again in both mod threads separately if it happens again.
