Oke, Im not sure if i can help you here but I can share some info with ya. Renal Bloodscalp is NOT the main set of quests in the chapter. He works for Aran Linvail. Is the Linvail quests that you have a choice over working for Bohdi. You can work for either one but not both. If you agree to work for Bohdi and have chosen the evil path. Not that working for the shadow thieves is alot less evil or anything, but shes just more evil than Aran Linvail.
Are you going to the correct part of the docks to get the cargo??
Do you have the patch??? do you have any other updates or anything???? I think the engpatch can be found on the front page (or a link to the patch anyway) here:
