Since returning to the game a couple of weeks ago with a clean quest slate, I've run into some issues with merchant quests. By these, I mean the ones that used to give "merchant" faction points, or which are given by merchant NPCs.
Basically, the few I've managed to get don't give faction points of any kind anymore, and here's the key part:
Most merchants won't give me quests at all, not even basic "kill some rats for me" ones. In particular, no merchant in Ojaveda will give me quests. I've tried Jirosh, Trasok, Brintec, Bjorid, Brado, Vladovic, amongst others. These all used to have some basic quests of the sort that you'd think wouldn't have a lot of prerequisites.
On a similar note, though it's not for a merchant, Rylour won't give me his quest, though I've done lots of BD guard quests.
Since the decisions you make on quests now matter more than they used to and are better tied to roleplay, I am loath to simply do every quest in the game just for the hope that one might be a non-obvious prerequisite for another. Nor do I really want to do quests that are not connected to who my character is, or be forced into in-quest actions that go against my character.
