"Vampirism" Effect

In Vampirism, when ever somebody dies, the map gets revealed then hidden again. I cut that part out, but there's one small problem - I don't want the structures to get revealed, but in fact remain hidden.

I messed with the contrast a little to make it easier to see.



Ok, my question is is there a way of preventing this from happening?

pick all buildings and hide it when your reveal the map, then unhide it when you set the fog of war again.

Hm... it seems to work...
