Investigating the Merchants' League Estate quest bug

[Hekemon]

Hi,

I'm unable to finish this quest. I talked with Aldeth and Brandilaar in 2nd floor, gate the evidence to Aldeth, went upstaris, killed all dopplegangers. Now Alderaan still claims "monsters still live" and Brandelaar ask for evidence I don't have anymore. Downstairs is like nothing happened. Guards and merchants are still there.

First time I failed trust of Brandilar and couldn't complete the quest. I showed letters to Aldeth and lead into situation where everybody goes upstairs to party where people turn into doppelgangers, I killed everyone in upstairs but Aldeth claimed "monsters still live"

On second time I managed to get trust of Brandilar, showed him letters first = Zorl turned into doppelganger in second floor, there were doppelgangers in first floor and there were doppelgangers in third floor. This time killing all doppelgangers resulted Aldeth complete mission.
