I play with full help on generally. Today I went into Elmussa Damori's house. When I examined a chest it said first that it was owned by her, but with a second line below that: "Global Ownership HHCS" As far as I can recall, I have never seen this information come up before. Any idea what it is? I assume that "HH" means "House Hlaalu" considering her connection to the quests.
Sounds like a mod I don't know. Folks over at the mod forum should be better suited to answer that. If any moderators agree with me on that, then your topic could be moved.
Oh and be sure to post your mod list from inside your Morrowind.ini file.
