Edit: Solution (through clua console) is on my third post.
I'm currently trying to do the Nalia's father funeral quest.
After accepting her in the party, the messenger showed up at the slums. Then I proceeded to the graveyard district where the messenger teleports everybody to the funeral building. I tried speaking to all NPCs in the upper level, using each party member (Nalia included). But Isaea Roenall never triggers into leaving, he always have a 1-line speech no matter who I use to talk to him.
I also tried letting Nalia go by herself to this freaking funeral. She states she will be back in a day at the copper coronet and leaves the party. Unfortunately she never returns, I think she was abducted there
So I'm stuck in both paths, there is no way to advance the quest further.
For Path 2(Nalia goes alone) I tried using the clua console in 2 ways:
1 - To spawn Khellor (Roenal's traitor guard), which resulted in Nalia prompting her return-from-funeral speech when I reveal Isaea's slavery in government district. And later more creepy things occur.
2 - To spawn Nalia after 24 h, using these lines that I found on another forum:
Nalia returns and after a while Isaea appears for the ambush, but he stays motionless and I can't talk to him.
I have BG2:EE with no mods installed.
