Single Mission Menu Briefing Bug?
 

The 'briefing' for any single mission I open (after launching the game) appears for all other single missions. Not sure if this is a bug or an install/hardware issue - anyone else experiencing this?

Yup, it seems that they get stuck to the briefing of the first mission you run in each gaming session. Campaign briefings work fine though.

Thats a relief, thought my install was corrupted!
