Replay messing up.

So I've started a campaign as Middenheim, third turn I attack a rebel village south-east and had a nice battle with hardly any loses and not a "Serious" playstyle.

I thought "Lets look at that battle again for some nice screenshots".

Then, an massive nucl-..

Alright, alright, there was no massive nuclear explosion...

So the replay starts up and I'm looking at the beginning how I was setting up my troops for the battle, but noticed that they were all being thrown around like a pair of dices.

The screenshot of the "Correct" unit positioning:

instead, it positions the units like:

And the game crashes.

My question is: Are all replays like that or was it just a matter of bad luck?

Thanks in advance.

P.S. The units were:
