If you change the mesh ID of a MeshPart to a mesh that was not uploaded as a MeshPart (e.g the mesh of a hat), studio will freeze when you use the move/scale/rotate tools and grab the handles. Doesn’t happen when MeshPart material support is disabled.
Repro attached. Just open it up and try to move/scale/rotate the MeshPart with the handles.

There’s also sometimes a weird stretching effect just as it freezes if there’s a part with a SpecialMesh using the same mesh ID.
