Update is live and everything seems good now.
The issue was caused by a bunch of incompatible vanilla lowpoly imposter models that were tied to the riders.

Issue confirmed.
Will fix.

Viewed from a particularly distant place, the farther it is, the more obvious it becomes

When War Ox Riders fight and die, if you zoom out and rotate your perspective, you will see large torn models, like lasers shooting through the sky，I tested it with only this mod enabled

I just double checked in custom battle and everything looks fine.
Well, aside from armour clipping and weird looking oxens' necks but those are known issues since release, none of the crazy stuff you are reporting.
This pretty much sound like either Steam failed to properly download the mod on your end (aka corrupted files) or you are trying to use another big mod that is currently affecting most of your units' animations (both vanilla and custom ones).
Normally this wouldn't be a problem but since many big animation mods still didn't make the jump to 4.0, heavy visual glitches can be experienced if you keep using the outdated versions.
The first big animation mod that could cause something like you are describing and that comes to mind is Matched combat, which still need to be updated.
For future reference: when posting a mod's bug report it is ALWAYS better to test the game with only the suspected mod enabled and see if you can replicate the issue first.

Hey, I just wanted to report that this mod is super glitchy. When they are attacking and die their bodies spaz out and go crazy.

It is with a heavy heart that I must inform you that I will not be updating any of my mods in time for the Chorfs update because my potato PC has finally left me after years of honoured service.
I have already found a replacement, but since I still need to know the shipment data and because of other shenanigans going on, I can't give you an exact ETA on when I'll be back.
You have my full permission to take and update any of my mods, but keep in my mind that I'll be back eventually and I'm going to update the OG ones.
Now I know that some of you might want to leave a comment to cheer me up or ask me some questions but please DO NOT do that and keep the comment section clean so that people can read this comment and understand why I'm not updating my stuff.
Thanks for all the support and see you again when my new rig arrives.

Thank you very much!!!!

Yes plz Cataphs estalia bull warriors

Yeah, a similar unit for Empire-like factions would definitely doable.
I'm mainly interested in making submods for Cataph's Southern Realms when we are talking about specific TEB units though.

Any chance of a unit ofr TEB like this?

Interesting. I will be monitoring this!

Very cool

Thank you!

Seems about right. These Oxes should be slower than horses but they should be sturdier and hit harder on the charge

Sounds fair, will do.

Another cool mod my friend!

May I suggest reduce the speed to like 60 and add strong vigour because ox?
