Line Infantry attack animation gets stuck on the walking animation before and after attack, takes around 8-15 seconds for the game to end it

Whenever I use line infantry, the animation gets stuck on the walking animation, almost as if the game is being blocked by some invisible wall causing one of the soldiers to not be able to go to the end spot of his animation. Any idea how to fix, and is this a common glitch?

Same problems with scouts.
