I cannot see my objects that I created in BluePrint Class

[Mikevandoorne]

Inside the BluePrint :

1. Go to Viewport TAB
2. Click on a Component,
3. Then Click in the viewport ,
4. Then Hit F (focus) ,
   and BAM! everything is back!
   At least that worked for me after 2 days of searching,
   remaking my complex blueprint and end with an out of focus problem grrrrrrrr.
   The key part is:
   DON’T FORGET TO CLICK IN THE VIEWPORT AFTER YOU SELECTED A COMPONENT,
   then hit F , if you don’t click in the viewport (on a grey raster area) , F will not work.
