Exact steps for others to reproduce the error
- Create plane object.
- Extrude vertices so it looks like cube.
- Bind it as "mesh object to deform with". It works.
- Remove extruded vertices so it looks like plane again.
- Extrude vertices again so it looks like cube again.
- Bind it as "mesh object to deform with" again. It doesn't work.
