From http://wrye.ufrealms.net/, GMST Vaccine (http://wrye.ufrealms.net/GMST%20Vaccine.html / http://wrye.ufrealms.net/#NotesandUtils):
There are five scripts in Morrowind.esm that are either not compiled or not correctly compiled. While these scripts are corrected in the expansions, if you only have Morrowind.esm loaded in TESCS and you do a compile all, these five scripts will compile (or try to compile) and will become a part of your mod. This is called the "SignRotate Contamination" problem (named after one of the five "dirty" scripts). Like dirty GMSTs, these dirty scripts should be removed from your mod before playing.
However, these dirty scripts can be vaccinated against in exactly the same way as dirty GMSTs. To wit, GMST Vaccine.esp now contains the corrected and compiled versions of these five scripts (DagothUrCreature1, EndGame, Float, LorkhanHeart and SignRotate). So, with GMST Vaccine loaded, these scripts will recompile without error, and so will not be added to your mod when doing a compile all.
0-02 Script Vaccine 9/30/2006
- Added script vaccines
- DagothUrCreature1, EndGame, Float, LorkhanHeart, SignRotate
- Note that GMST Fix does not contain the script vaccines.
So I would say that one of the easier way to fix the "French Dagoth Ur" (apart of fixing the mod itself) would be to use GMST Vaccine (but not GMST fix which is also included in the download) with its date changed in order to have it loading at the end of the mod list (or at least after Ald Vendras and any other mods that contains those scripts).
What do you think about it? :unsure:
