Cool, this is news to me. Is there any impact on FPS because of this?
Sorry, let me clarify on the Mournhold issue (we do have a FAQ about it on our website, and have had one for the past several years, in case people didn't realize that.).
We have not remade Mournhold or expanded it(@Yeti: Mournhold is not a city, it is simply the capitol of Almalexia, which is the capital city of Morrowind, so Mournhold is part of Almalexia) or opened it or modified it, largely as per our policy of "Don't mess with Bethesda's work."
What we HAVE done is three things, two of which change the vanilla version of Mournhold:
1. Added special "behind-the-scenes" doors to the interior cells of Mournhold (they won't show up on your minimap, don't worry!) so that when visiting it while playing TR, your map won't show you being in Ebonheart, but actually in the middle of Almalexia.
2. We are scripting the Gates of Symmachus to be unlocked permanently (not counting any big quests that might require the gates to be temporarily sealed) ONLY once the player has completed the Tribunal main quest. This way, the player can travel from Almalexia to Mournhold and vice versa through the Gates, without having to go through Ebonheart.
3. We have created an exterior DUMMY version of Mournhold, for the sole purpose of distant land creation with MGE, so that people who are standing high up and look toward Almalexia won't see a big, brown, empty circle in the middle; they'll see what looks like the capitol of Mournhold.
Levitation will be banned (and jumping may or may not be capped, I don't think that's decided yet, but I'm leaning toward not capping it in Almalexia proper.) in Almalexia, just like it is in Mournhold. Even though through certain MQ events, the ban should be lifted, no one knows, or believes (if you tell them what happened) that said MQ events have transpired, so there's no reason to lift the ban, from our point of view.
Sorry to disappoint anyone who was thinking otherwise, and I hope this clears things up a bit.
