Problem with swapped Clarie head mesh.

Hello!

I'm make full swap mod in "Resident Evil 2 Remake". I'm download "XNA Lara XPS" free model and inject meshes and textures in "pl1000" game slot (for swapping Clarie in jacket). Also in slot "pl1050" i'm inject new head with eyes, teeth and tongue. I'm adjust and transfer weights in "Blender 3.0". Inject meshes and textures in "Noesis" with "fmt_RE_MESH.py" plugin. In "Blender" i'm transfer weights on my new model head from original Clarie head. My new mesh weighted correctly: he don't have any ungrouped verticles, he have all face vertex groups (cheeks, nose, lips, eyelids and other), 4 shoulders vertex groups (l_arm_clavicle, r_arm_clavicle, l_trapA_muscle, r_trapA_muscle), head and neck vertex groups.

I'm cut head mesh near and little above cut-line of original Clarie head.
But in game i see few polygons, penetrating through body mesh.
Body mesh is normal. This penetrating long polygons from head mesh.

If i'm decrease neck polygons (almost remove mesh) from head mesh and put neck polygons to body mesh, all work nice and penetrating polygons disappear.

What i'm doing wrong? Help me, please! This penetrating polygons seems like unweighted or weighted to wrong rig bone.
