Sauron unit editing problem in DAC 4.6

[Dominique le Malade]

Recently I've been editing the Mordor roster of Divide And Conquer 4.6 to my liking and I can say that I'm little displeased with the Sauron bodyguard unit.
I am trying to alter it to be like the Massive Overhaul Submod 1.7 one (it's probably the same in vanilla TATW but i wouldnt know since I have never played it) which has a single elephant type Sauron unit.
I've made the supposedly appropriate changes in EDU and unit_models files. Everything seems to be in order, but the game crashes upon launch after I make the EDU alterations.

Here are the changes that I've made.

I also noticed that "unit_sprites/sicily_eeents_infantry_sprite.spr" is missing in both mods but it seems to work properly without it in MOS 1.7.

Am I missing anything, or is it just not possible to add that unit in DAC 4.6?
If anyone can give me some advice or help me with this, I would be very grateful.

Thank you for reading and have a great day!

Can you tell me exactly in what file you did this? Because, in DCI: Last Alliance, I have the same problem. "Sauron Elephants" is buggy because they used and modded a bodyguard Sauron. Please can tell me the path of that file of Divide and Conquer. I think it is the same as Third Age 3.2. Also, you can take advantage of this and maybe you could try creating a fixing submod.

[Dominique le Malade]

I did these changes in two files. Firstly, "battle_models.modeldb". For DAC the file path is "Medieval II Total War\mods\Divide_and_Conquer\data\unit_models".
And secondly, the EDU which is an acronym for "export_descr_unit.txt" located in the data folder of any m2tw mod. So in my case "Medieval II Total War\mods\Divide_and_Conquer\data".

This guide helped me learn about these files and more so I can edit the game at my leisure. The basic stuff is really not that complicated at all, and you can learn about it very quickly. For me it took only a few hours to become an adept of text file editing, although, I still have a lot to learn. So here you go. https://www.youtube.com/watch?v=NktA...ErGaludirithon

As for creating a fixing submod, I don't know if I would be able to do that with my current skillset in modding. For now I'll try to find a solution to my current problem, and if I do, I'll definitely make sure to post an explanation of it here.

I finally got this to work! In the decr_mount.txt file of DAC, the sauron entry name is "creature_sauron".
I simply made the change in EDU
from:
mount sauron
to:
mount creature_sauron

I got mislead from MOS where it's simply "sauron", and assumed it would be the same in DAC.
