A bug regarding Spies/Treason

Hi,

I've been playing AoE2 for about a year or two and I didn't notice this bug
before, until a few days ago. I couldn't find Microsoft or Ensemble Studios'
e-mail support or bug report, so I wanted to share this with you guys.
It's pretty simple. The easiest way to test this is with cheats, by the way.
When I research Spies/Treason in single player random map game against
computer opponents, the enemy should reveal and uncover map for you, right?
It does uncover the dark areas of the map on the game view as I watch the
opponent's Scout exploring the map, but on the mini-map it doesn't uncover
and reveal those dark areas! Only gold, stone, deer etc. locations! But when
I click on different or even the same map view mode button (Combat, Economic
and whatever are their names...), the dark areas become uncovered like
supposed to! It looks like the game doesn't refresh the mini-map view
regarding the dark areas!

Could you check this out?

Thanks!
