[z2529] Revert "[z2518] Fix problem with scaling vmap model. VMap and MMap DOES NOT need to be rebuilded."

This reverts commit 9319cf0e6a651d8068e1d534dbd22d978df38946.

Seem not stable enough so better to revert it.
(extractor binary is updated too)

Thank to @Beerfish, @Metal, @shnibble for their feedback and patience.
Thank to @Castro for its help to identify the commit problem.
