Sarco behaves strangely at the cave entrance.

When entering or exiting a cave small enough to require crouching, the Sarco exhibits behavior that ignores the terrain; while moving in a crouch, it floats upward as if drawn toward the ceiling. In some locations, the Sarco's body may even become completely embedded within the rock, rendering it invisible.

When testing in the caves located in CF and PI, the same phenomenon occurred in both instances. I also tested other playable characters (such as Sty), but only Sarco triggered the issue.

This glitch can be exploited for surprise attacks and should be fixed. Once corrected, the Sarco should behave realistically and be able to enter and exit caves smoothly.
