Character clips slightly into ground randomly

Hi there!

I am making a game where the player is able to transform into a static mesh they select (Think prop hunt). Occasionally, when the character is transformed, if he jumps and lands for whatever reason, they may clip into the ground about 2-3cm. This causes an issue for static meshes that are thin like plates, and cups because the ground is then clipping through the mesh, but is not noticeable with other meshes, or with the character mesh.

I have been developing this game as a hobby for 5ish months, and this problem still plagues me.
