My top 3:
1. Invisible units bug - the game doesn't display graphics of enemy units. Game losing bug, especially on higher difficulties.
2. Jumping from unit to unit in most ridiculous way - annoying as hell, makes militaristic games last double time they could.
3. Workers stop working when enemy AI unit is like 5 tiles away without possibility to do any harm, but when CS units approach the workers don't stop even when the CS unit is a tile away.
