My party was NE. I went to the guards tower and took the quest that should tell me that two merchants are bad. So i went to the camp. Talked. Got the info. Went back to the tower. Told them. Now after a while , couple of days. I went to the merchants talked to the first one (forgot name) and i told him that "i know" and i took 100gold and he even told me about a quest. I took the quest. Talk to the other merchant. He knew i sold them already. Talked back to the first one... he also knew. What is strange that this quest (even before talking back to the first merchant) is still listed as not done BUT there isnt any description nor title to the quest. Just blank. Bug?
Which quest isn't marked as done Havoc? The one Burne gave you, or the new one which the evil traders gave you? edit: thanks to rufnredde and Blue, problem has been tracked down. You need to download the cumulative fix pack called v5.0.1 which is over in the general modification forum. The problem is caused by a totally different quest. The assassination quest hasn't been implemented yet as an actual quest series. Although it may get done one day
