First the Length of the title is too short to accurately display the bug
it should read :
[V20 Stable 05/01/2014-Ground Combat] game freezes for 5-10 seconds every time a soldier dies and the death animation is played
I started a new game ,managed to intercept a fighter ( it was the first fighter I encountered) ,landed an assault team
one of my soldiers died 2 minutes into the level , the game froze for 6 seconds then I saw the death animation play and the game continued on
a second soldier died 1 minutes later , and again the same issue
hope this helps
