Problem: Abandoned tanks becoming destroyed without any reason...how?

[Taskforce]

During Battle 1 of my new AAR series I not only managed to force a Soviet' T-34/76E M1942 crew to surrender, thus capturing the tank, before that a KV-1 M1942 and a T-34/76 M1943 were abandoned by their crews and should have been left that way, since my infantry continued to push forward and stopped any possibility for the crews to re-claim their tanks.

Still I "only" ended up with the T-34/76E M1942 tank as not destroyed and saw the abandoned tanks going from abandoned to destroyed, including the fire ontop of the turret.

How is that possible? It has never happened to me before, not even during my "Final push for Berlin" AAR.

I'm still going to include the other two as captured, of cause, but still...how was this even possible?

During the same battle the crew name and registered tank kills of my first StuG III, knocked out, were changed to something else and the 3 kills becoming 0 kills.

How were these things even possible? I've never encountered this kind of problem before.

When I re-installed the game after the strange virus I followed the correct patch order, so that shouldn't be a cause either.

Cheers, Taskforce
