People, please forgive me if this has been discussed before.

I find that I get a very common CTD when playing RTW.

When using a ram that has just punched through the wall, I click on the troops controlling the ram to get them ready to bust through on the poor hapless gauls/greek/insert random faction here and I get a CTD.

It only happens when I get a bit eager and try to redeploy the troops BEFORE they have dropped the ram. I see the little triangles showing where my troops will go (and a big triangle - being the ram) then a flicker and I am out of the game.

So,
1. Is this a well known bug?
2. Is there a fix?

Thanks in advance.
