1. Tremorzilla is unable to hit giant mob such as Atlatitan, Lux, and even Giant, with their heat ray, unless if the player aided TZ with their aim (this probably also happens to other giant mobs in different mod and this bug might occurs because only in certain spot of hitbox can be hit with TZ's heat ray)

2. second bug is that Tremorzilla's swimming animation is a bit glitching when we ride them in the water. Their head, legs, and arms are vibrating and refusing to play the animation unless if we un-ridding it
