With TR_Mainland.esm from the 20.02 release enabled, every single time I ask a NPC in Dagon Fel or any of its interiors about "Dwemer ruins" they all just spit out the same word - "DELETME". I have the slightest gut feeling that this could just be placeholder text that was accidentally left in but I'm not entirely sure. I first noticed this in a modded installation I was putting together but I'm still getting "DELETME" as a response in a freshly installed GOG version of Morrowind with nothing but the standard Bethesda .esms, Tamriel_Data and TR_Mainland ticked in the launcher.
When reaching the fourth stage ( TR_m1_PT_MaI_4 ) the first step, index 10, it is unlisted from active quests and shown as finished. I'll update once I get a command spell to see if it is still finishable.
Shara Mantiti's House. Her door is on the outside of a pod, without any walkway. You can float to it. If you exit, you get placed somewhere on the floor outside, precisely below it.

There is an issue updating to Index 85 in the quest after killing Devas Terano. When Talking to the Daedroth you receive the message you see in the screenshot. I was able to bypass this by using a console command to update to Index 85.
I tried to follow the quest instructions. Heading to Baelkashpitu as soon as I killed Devas Terano, having the Soul Anchor in my inventory. I talked to the Daedroth with the weapon equipped as well as out of my hands.
Another thing to note is that after waiting for 3 in-game days, the quest does not fail either.
I just joined Telvanni at the council house in Port Telvannis. I have not touched any Telvanni quests on the mainland. I talk to the various Mouths to receive their quests, and then click on "join House Telvanni" which is available despite me already joining. The NPC (doesn't matter which of them, the behaviour is the same) says I am already in, but I get stuck in dialogue with two options "Yes I'll pay" and "nevermind". Neither option gets me anywhere, and dialogue is stuck.
