Very high ping in test environment

Hi, im currently working on my mod which adds this boss mob which uses a ghast custom model i made in blockbench, i gave it the ability to shoot custom projectiles and the problem im having is that when its shooting it causes INSANE lag, like not low framerate but kinda like internet lag.

I mean the time stops for a moment and then everything happens fast usually resulting in death.

Here are screenshots of the AI tasks and procedures tab

There's no problem when the boss is simply moving, but the lag starts when it begins to shoot its projectiles.

Btw, i have no global every tick update procedures

If this matters, the MCreator version is 2021.3 and Minecraft version 1.16.5
