During the third challenge for "The Sorceror's Apprentices" quest, I gave Saturius the Scroll of Icarian Flight befor ethe duel started. As expected, Saturius launched Kelkemmello up into the air, but when he fell back down, the impact killed him, ending the challenge with no reward. I know he's supposed to survive so that Saturius can properly become the court wizard, but I'm unsure of how to save Kelkemmello without breaking the quest.
Entrance to Drenka Cavern (Boethiah's Spine 24,11) is almost blocked with a cliff (It's right between Tel Oren and Ranyon-Ruhn, a bit closer to Tel Oren). Not sure if it was intentional.
In the first quest of the Imperial Cult questline, Allion Aberius directs you to visit the Soludanni Egg Mine. If you do that, you get a topic 'Han Sadalvel', which contains the following: "You've been sent to Soludanni Egg Mine? The simplest way to get there is to take the silt strider -- it's quick and cheap." From my limited understanding of the CS, this particular topic is filtered for Bal Oyra. The issue is that there is no silt strider in the vicinity of either Bal Oyra or the Soludanni Egg Mine.
I found a <deprecated> item in a barrel in the Firewatch docks. It's ID is t_ingwood_meatratroast_01. It was in one of the barrels on the first, left-hand section of the docks, if coming from inside the city. See the attached screenshots.
Dral's mouth gives chores dialogue as if he knows the player wants to be a hortator after the player recieves moon and star. It was done to reflect the fact that Dral gets disabled, but I propose at least changing the lines to say that Dral is simply absent instead, because the player is not necessarily doing the hortator quests.
So I found this potion being sold in Old Ebonheart and since I'm playing with the Atronach birthsign I figured I could use this without the negative effect for obvious reasons. Well apparently consuming this potion and waiting for the "stunted magicka" effect to wear off will result in an Atronach character without stunted magicka! The effect is still listed but upon resting magicka will actually replenish. It's probably a good idea to replace the effect in said potion (Llotham) with drain intelligence. Cheers
The velk have a script to detect the grievous crime of attacking/killing them. Unfortunately the container it uses get locked with a level (100) higher than the designated Open spell can open meaning no crime is ever detected. Solution: lower the lock level. Container is missing ownership, but failed lockpick attempts not being crimes was also an openmw engine bug
TR_m3_Valvramu Ullev has a "thanks for doing the quest" type response for TR_m3_Do_Velk that's improperly filtered. It shows up even when the player declines the quest.
