Hlan Oek dockworkers say "I don't want to face Gidain's wrath" during the Tainted Waters quest. This sentence is a bit unclear because the player will almost certainly forget who Gidain Verayn is at that moment. To fix that, they should say "Gidain Verayn's wrath" or "the wrath of my boss, Gidain Verayn"
The door marker in the canalworks tomb cell should be moved near the door. Currently, upon entering it, you appear next to a wall, being a bit stuck in it.
I'm not sure why this happened, but the intended line for Gilner Herano about "Camonna Tong" was set to be a 50% alternative line for Lloden Dadry instead. This makes no sense in context. Gilner is the one who has three children who are CT members and who come up in the questline. Lloden doesn't.
Outside of Shaden, a cave on the Armun-Roth Roryn border, there's a kagouti den. And in that den there's a skeleton with an arrow through his head. In his inventory he has a vanilla key to Vivec underworks.
The skeleton should be replaced with a different one.
Material Matters, a quest given by the Andothren smith, Ulran Teryon: he greets you, a stranger, with a confession that he's sold a bad merchandise that's probably led the buyer to death. I suggest to at least gate this greeting to a certain level of disposition (70?).
A longer alternative would be to start the quest by introducing the quest topic in general city greetings (for ex. "Our local smith, Ulran Teryon, keeps asking about a certain western crusader. He seems concerned but doesn't tell why".)
