[1.16.5] Rollbacks, can't call horse, can't set personal horse, and duping of horses

[AlexE7Pilou]

Hello, that's a long issue title, I'm sorry, but it's all the issues I'm having

I'm playing on a server with friends, and recently, I found that I couldn't call my horse, and it would TP me back to the place where I dismounted my horse for the last time.
It woudl says : "You can't call your horse in this area". After this, I can't break blocks, nor interact with entities, blocks, anything.

After disconnecting and reconecting back, I back on my horse.

I can't set a new personal horse, it'll says : "You can't set your horse in this area", and give me the same bug as above, can't interact with blocks, TP back to last location, etc...

And I recently found that I now have 2 horses, same stats, same custom name, same stats. The mod duped my horse. (During recording of the bug, I found out many others horses, I think maybe arounds 6 or 7)

File is too big to be hosted on Github, so I hosted it in discord CDN

We play with many others mod, I don't really know if it's compatibility issues between mods, but no other mods interact with horses
The mod is installed in the server, and in client
