Tyrannotitan Heavy Bite: inner mouth model protrudes through lower jaw when facing right

When Tyrannotitan faces right and uses Heavy Bite, the inner mouth model pushes outward on bite impact. It penetrates through the lower jaw mesh, creating a visible clipping glitch. This only triggers when facing right; left/forward directions animate normally.

Every Heavy Bite cast facing right causes abnormal stretching of the oral model. At the moment the bite lands, inner mouth geometry breaks out from inside the lower jaw. The visual artifact is obvious during the bite-down frame of the attack animation.

The Heavy Bite animation should render correctly in all directions. The inner mouth model must stay within the lower jaw throughout the whole attack, with no geometry piercing or protruding outside the jaw mesh.
