Placing the 10 rusty dwemer cogs into Eraven's special crate doesn't activate Journal entry 30, causing a dialogue loop with Eraven Arns whereby responding 'yes' to his question makes him repeat the question and doesn't advance the dialogue or the quest.
Additionally, near the crate with the rusty cogs there is a severe floater next to it - ex_barnacles_04
When encountering the two murderous vigilante Argonians (Heem-Wan and Illisheeus) for the bounty given by Ando Imp. Legion - their victim's body is halfway into the mountain. Granted, maybe they dropped the mountain on him.
Victim's body is cut off from the ribs up inside the rock.
Another note, related suggestion: The female farm owner who you can talk to has no reaction/chage in dialogue when clicking the prompt of the victim's name.
Banvira Auctoria will mention you "dispatched" him. It's technically possible (if overly annoying), to get the report without killing him by calming him and pickpocketing him. Since the quest mentions you'll "probably" have to kill him (not that you will), it's actually something a player might try to see if it has unique dialog.
When seeking advancement to Wizard in the Mages Guild the player needs a Wizard's Staff. Mainland guild members will still direct the player to a cave near Dragon Fel, which can be ludicrously far away for them to have heard of (in-fact, the vanilla dialog here doesn't actually mark Dagon Fel on the map, making it even more absurd for people playing characters that never step foot on Vvardenfell). This seems like a simple place to add another "free" Wizard's Staff for the player to be directed to if they seek advancement in a guild on the mainland (or at least southern mainland.
Hands are invisible in 1st-person when playing as a male or female Dagi-Raht in the vanilla engine. I marked this bug as minor since it only appears with third-party mods that make the Dagi-Raht race playable.
The quest for general Casik (Belated Justice) and the one for Bera (The Exiled Duke's Affair) result in very similar rewards
The main NPCs from both quests reside in the same cell (Old Ebonheart, Legion Dungeons) and both quests reward the player with an amulet that increases personality and/or speechcraft
There are more items in TR that have similar effects, most of which are amulets
here's a longer list of kinda similar items, the first two are the one from the quests in OE dungeons, the first four items are amulets:
When TR_m4_Duvlas force greets you after asking around for a while all is fine. However if you kill her in one shot the script goes into a state that causes every dialogue related action to hang. This gets saved in so after saving the savefile is corrupt too. This goes all fine if she does not die at once.
just a wild guess but:
if ( doOnce == 1 ) if ( GetHealthGetRatio < 0.25 ) SetFatigue 100 ForceGreeting <= NPC is allready dead? return endif endif
