Unable to find Region 'Sea of Ghosts Region' in Load for Cell 'Wilderness'.  means that TR_Mainland is loading before Tamriel_Data.
The regions are defined in Tamriel_Data and if a cell has a region id that doesn't yet exist, it will produce exactly this error.

Check the dates on your files (or load order in Wrye Mash). That might also cause some of the asset problems.

Hello Folks,

I am encountering a similar problem. I am only using the latest Tamriel_Data.esm, TR_Mainland.esm, TR_Preview.esm, and TR_Travels.esm. Latest Morrowind code patch also used. 

Error is: Lots of floating question marks, lots of error prompts (seems to most be meshes).

- I have updated Morrowind.ini to include the PT_Data and TR_Data bsa's. 
- I have used wrye mash to ensure load order is correct (Morrowind>Tribunal>Bloodmoon>Tamriel_Data>TR_Mainland>MorrowindPatch>TR_Preview>TR_Travels)

Possibly area causing the issue - I am not really sure how exactly to use wrye mash, and I have simply changed the various esm file dates such that they load from oldest to newest? I cant seem to find any clearly laid out tutorial on this specifically. 

I am using windows 10, and installed through Steam. However, it is important to point out that I had Tamriel rebuilt version that I downloaded in ~July of last year working just fine - this clean reinstall seems to be the issue (multiple reinstalls).

Any thoughts? Am I using wrye wrong? Am I missing something else?

Cheers,

PT_Data.bsa and TR_Data.bsa are both in the Data Files folder.

I've attached a screenshot of the morrowind.ini file. The load order is as seen before - however, have a look at the order shown in the ini. Does this have any bearing over load order? Or does the order seen in the launcher the actual load order? I have tried rearranging that list to a proper order, but still not working.

I tried copying the morrowind folder outside of program files, but get an error running the game (probably some appdata issue, would have to actually install it outside of program files, but steam doesn't allow that). 

Another possible avenue I will have a look around at - when I edit morrowind.ini for the first time, a prompt from steam comes up. It asks if I should upload to the cloud, or download from the cloud. I select upload, but perhaps it isn't properly saving because of how steam preserves core game files... 

I had initially been trying on old save files, but this occurs when starting a new game as well. Have not had time to try anything else yet - may revert to old version soon and get back to playing. I seem to recall having the same issue last year, wish I wrote down how to fix it!

Ah, finally, I figured it out.

It was regarding the Morrowind.ini file:

The tutorial outlines exactly what to write in (as you can see in my attachment above, it is correct). However, it says that [Archives] is located directly above the [Game Files], right at the bottom. If it is not located there, it says to then add it to that line (Or maybe I am crazy and hearing things). Anyway, that is what I did - but there is an [Archives] located elsewhere in the Morrowind.ini that was not getting updated (never thought to look). 

So, simple mistake on my part. Thanks for all the help.

@ Kinky Kong Keith  I can find the textures (at least the TR_C_RobeCommon02 ones) but it seems they're being looked for in the root folder whereas they're now in TR\c\ in TR_Data.bsa. Might be something that happened during this change on TR's end.

edit: yes, known issue with better robes. It doesn't look like an automated patcher was made for that, sorry.

I have the compataiblity patch that comes with Better Robes. but didn't have it installed on my latest playthrough because there was some issues with it. I'm assuming that's what needs to be updated?

And what about the Tel Darys issue? That very same issue is also present at Tel Aranyon. 

If your problems are related Tel Darys, Tel Aranyon and other related Telvanni towers, you are using an outdated version of Uvirith's Legacy. Please make sure you are using 3.51 and clean your save game as Rot said.

For Better Robes (TR Patch), I've gone and changed the paths and filepatched the esp. Since I don't use it myself, please check out if this corrects all the issues. If it does, I will upload it on MW Nexus for other people.

You can try this for the missing hallways in Tel Darys (use instead of the TR addon that comes with UL, it's the same with an attempted update to 16.12),
Might not work in a savegame in which you've already visited Tel Darys:

Ok, entirely new issue, that completely breaks the game. I decided to reinstall everything after issues with another mod (Vadul Tharis's Redoran Expansion to be exact). Well, I fired it up and this error pops up. 

Expression Error Unable to find cell id "Telvanni Library" in script TR_m2_TelvLib_NoTeleport

It crashes the game every time I try to start a new game.

Bumping this thread because I'm getting the same error. I'm using only TR_Mainland on a fresh Morrowind install with the only other mods being MGE XE, better fonts and the Morrowind Code Patch. To summarise what I've done so far:

• I've registered the PT_Data and TR_Data BSAs in the Morrowind .ini file. 
• I've tried various things in Wrye Mash, but it has yet to detect any problems. 
• I've regenerated distant land meshes and textures in MGE XE to verify that it wasn't causing the issue.
• I've uninstalled and then reinstalled the Tamriel_Data and Tamriel Rebuilt mod files in the Morrowind directory, running Morrowind in between additions
• I've been activating the mod files one at a time and then running Morrowind, to check that the issue wasn't in the Tamriel Rebuilt .esps

At this point I'm not sure what I can do short of straight-up reinstalling Morrowind, but I can't see that solving my problems.

My current load order according to mlox is this:
_001_ Morrowind.esm
_002_ Tribunal.esm
_003_ Bloodmoon.esm
_004_ Tamriel_Data.esm
_005_ TR_Mainland.esm
_006_ TR_Preview.esp
_007_ TR_Travels.esp

The errors I'm getting are various model load errors in the Meshes/TR directory, as well as animation errors on creatures.

Tried that as well, but it didn't fix the issue for me.
