Frequency: 100% of the time
Solution: Stun grenades canceling retreat seems fine to me, but players should be able to hit retreat again to continue the retreat.

Put on your nostalgia caps here... remember Soviet wire in the original Alpha when they were patches of wire that infantry had to crawl under? I remember Relic saying they were removed because they interfered with retreating units and caused feel-bad gameplay. The stun grenades are an even worse offender for this subject and I KNOW Relic isn't biased for Axis

Thanks!
