I am not seeing any replays at all in my WW1 PBEM games; just a blank screen saying "preparing replay" for 5 minutes or so, before jumping to my turn.
I am getting no feedback on enemy movements and attacks which is quite a disadvantage.
I get this with both 1.00 and 1.01, but only on my laptop running Win 7 64bit, not on my desktop running Win XP.
