I made another thread about this in the Third age sub forum, but i am posting here too in order to maximise my chances to get an answer. And besides, it's about text editing so it's fair game.

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.Attachment 366108
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!
