the second issue deals with retreating units and is a 1.03 beta addition. I think this is what is happening. retreating units get attacked again by the winning units at the beginning of each new day. I don't know why this was added but it needs to be removed.
what happens to me is that at 1 am each day i have a couple to new combats start. i then have to go into each battle and tell my retreating units to disengage the combat and retreat again. i had to do this for the total number of days that they are retreating, a lot of extra clicking to say the least. It ruins the game. i have also seen the ai vs. ai, just run over units and they disappear.
I have listed this in several other threads and i hope the DEVS are taking a good look at it and are going to remove it for 1.03beta 10.
We fixed the retreat problem in beta9
