But here is what happened to me: i had a sync bug also. We used the Pompack Method, with the turning off of combat report, for 4 turns. i even loaded the pwhex file send by my opponent, but the sync continue.
So, i deleted the game from my computer, after saving the files of the game in a separate folder. I reinstall everything, then upload in the good orders the patch (i am playing Stock), and then put back the files in the "save" folder. From now, in 40 turns, i had no more sync bug problems.
Of course if someone give you more accurate hints, it will be good for you, but may be you could try this ?
I hope you will solve this, as it is really a pain to play with such a bug.
Thanks for sharing. By turning off combat reports for about 4 turns I managed to (temporarily?) solve the sync issue but then I couldn't get the combat reports to generate lol.
I tried running the turn on my laptop which has a pretty fresh install of my Witp (CHS) and it still wouldn't generate reports, so reinstallation of the game probably isn't the issue for me.
I'm going ahead for another 2 turns or so with reports turned back on and see if the situation fixes itself...
Don't hesitate to ask on the "Admiral Edition Forum", as their is now most people on this one, and they are many people with great technical skill (wich i am not ) who will help you without any problem;
