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.
