Same unit sounds instead of random

[lsnoop]

When I played Panzer Corps (1.05 and 1.22, with and without extra sounds) I had this issue: during one turn several units had the same movement/attack sound instead of random. I searched through the forums and found another desription of the problem:

You can move the three and only for example hear one movement sound in all the three. So the game might not have load all of them in the first moves and it could have just loaded one of those when you've checked it again. With the attack sound it can happen the same, because , generally, you have three random sounds to be played. Only it's more heavier because you have also an animation file associated to it.

Was the problem fixed in Soviet Corps and/or latest patches? If not, can I somehow force preload of all the three movement/attack sounds and avoid this bug?

Thanks!
