User blog comment:Kingb10/Help Please - Discover Points and Relocating Buildings/@comment-3991817-20131030153940

The Discovery Points were part of The Great Explorer event. You can only earn points for the duration of such events.

And relocating buildings to open spaces is only possible if you have a road leading to that open space. Almost all buildings need a road to connect to and can not be relocated to another spot without a road leading there.
