Mesh gone mad after packaging

I’ve finally finished a “game” which basically is a tour around a house I’ve projected using VR.
everything work, light are built fine and material don’t show much problems wrapping meshes.
I packaged the game with no error, but as I open the app (for android) I find some errors on specific objects.

Does anyone know what is the problem?
another tip:
The bed was downloaded from a site of free objects and it was in.3ds
the kitchen was made with blender by me and it only includes those wood parts and the glass on top. the hoven, sink and hood were downloaded and added directly to the model. the tools are different meshes.
