Hi,
In 6.1 while playing the HRE, I am about 50 turns into the game and during the execution phase the game is getting hung up when Sicily's turn comes around. I have three other campaigns going and have not had this problem. Although, I have had a few hangups that lasted a minute or more, usually the AI phase is lasting only about 30 seconds for me.
This occured last night and I gave the computer about 30 minutes to work it out but no go. It was locked and I had to reboot. I reloaded the turn this morning and played a extra battle and still got the lock up with Sicily. Any ideas?
If someone is willing to try the turn on a their machine, I can email you the autosave.
