Game duration lockup

I have noticed something in Beta 3 and 4.

After I have played the game  for so long, say over 3000 turns, the game gets to a spot where it just won't do any more turns.  i can move characters about for their movement point allotment, even start upgrades to towns, but the turns will not process.

Seems to me that I remember something like this with GalCiv when it first came out.

I just want to say that i do hope that  you have that one taken care of before you release it.

Otherwise, this game is extremely well thought and executed,,I'm so glad to have gotten in on the beta versions.

I've given some limited input on this, but not a lot...

Thanks!
