Hi,

I'm running SweetHome3D version 4,5 on Arch linux at home.

I have created a house model. I start it in SWH3D version 4.5, then continue in version 4.6 then return to version 4.5.

This is because I move my work from house to the school and vica versa.
At school there is installed the 4.6 version.

So suddenly I have in this SWH3D dokument two identical house. How can this happen?

In 2D view I can't see the duplicate but in 3D view I can: one is close and the other is far.

What can I do to get rid of the duplicate of the original model?
