I fought a massive war against Lord Relias last night and during the many tactical battles there were 3 occasions in which tactical battle froze after killing a unit.

It seems to always occur exactly the same way and what happened in each instance was this: During the battle my unit delivers a killing blow. Instead of a single "whack" sound, there are two "whack" sounds when it dies. The unit that was killed then disappears from the field but yet the square he was in remains highlighted in red with the focus outline around it. Then the game just sits there like that. This happened every single time this occured. The only way to resume the game is to click the auto-resolve battle button, which works.

I suspect what may be happening here is that in some situations when a unit is killed that has counterstrike, it tries to counterstrike after it is dead and it goes into a loop because it cannot. Hopefully this is enough information to help track this one down. It's bound to leave a bad impression on those that encounter it.
