Some strange bugs in 1.19.2

[gusbaruc]

Minecraft Version: 1.19.2
Mod Version: 1.2.2
Mod Loader: Forge

Description:
When the Shattered spawns, it load texture by half until it moves. (First image) When moving, its texture loads completely again, as it should be. Probably if it sits still long enough, its texture will return to half. Another observation is that when you defeat him, he also only load half the texture, even if he had been walking with all the texture loaded. (Image 2)

Something similar happens with the Shriek Worm. He appears with the texture loaded normally, but after a while (since he doesn't leave his place) his texture breaks and looks like in image 3. An observation in this case is that he doesn't attack the player from the distance he should attack . I can walk close to him and he won't do anything. Unless I get too close to him. For him to attack me, I basically have to stay within his shadow radius (Basically glued to him). Another point of observation is that when executing the attack animation, its texture returns to normal. However, then, if the player moves a little further away, the texture breaks again.

To Reproduce:
Steps to reproduce the behavior: I explained everything above

Additional context:
I'm using this mod in a modpack, so the problem may be related to some other mod. But this problems didn't happen before 1.20 backport. I tested version 1.1.6 and it worked as expected without these problems.
