In the final dialogue with Vals Varano, you have to click on the "drafted the terms" topic, then select the "Why shouldn't I kill you?" choice, then click on "Bthuangthuv" topic, then choose "I bet I could kill you..." -> "Even so, I'm not accepting your terms" -> "No" dialogue choices, then kill Vals Varano and return to Bthuangthuv (no matter how).
In the final Ando TG quest, if you found Vilungil's ledger before speaking with Vendicci about "follow the money" topic, the same topic isn't available for Vilungil until you read the ledger again.
I found a bug during the Andothren Thieves Guild quest "Good Fences, Good Neighbors". The bug is regarding the NPC "Three-Eyes" that you have to recruit as a fence for the guild, whenever I tried to approach him my character would freeze up, but not my game. I could still access my inventory and the menu screen too, the music didn't stop either. When trying to speak with "Three-Eyes" you are also redirected to the previous dialogue box with the bosmer pawnbroker at the last stage you left it instead of accessing "Three-Eyes" appropriate dialogue box.
Difference between Hlaalu guard armor, especially in Ando and Narsis, might be confusing for players. A solution is to add a new dialogue entry in "Morrowind lore" topic explaining that.
While our line for once you've freed enough slaves to get told the code is filtered to the Khajiit local, the dialogue for if you ask about it before having freed 20 slaves isn't. That means any non-vanilla Khajiit says "The beast-folk tell of abolitionists acting under that name. Perhaps you should ask them."
When using Dovres Salvi's 1gp boat trip into Roa Dyr's canals, the stairway up and to the right from the travel destination has an invisible wall running diagonally towards the top of the stairs. You are forced to jump over this invisible obstacle to ascend the stairs. I can't tell if its a problem with the object itself because this ramp and another with the same bug both ascend west, while the same stair object mirrored and ascending east does not have this collision issue ocurring.
