Have to report a problem here: I play this game (with patch 2) with the Macedons for 79 turns now and today I've run in my first unplayable battle. I'm besieging Salamis and want to take it from the Seleucid Empire. I have 20 Units against their 24 (they have 1 Unit of Amoured War Elephants and 13 Units that come from the sea and 4 Ships). Battle startet as usual but always after their sea reinforcment arrived, all unit Animations got extreme laggy while the camera movment was normal (not laggy) and my units (mostly Pikemen) didnt do their phalanx formation correctly anymore wich surley would have lead to my ultimate destruction. Bug also occurs even if I lower the Graphic settings. The intresting is that I have played much larger battles in my campaign (for example 40 vs 40 units) with only normal Fps-drops (but still playable). I can remember that this bug also occured in a smaller battle against the arabian tribes where I was defendig Gerrha (where the enemy also had naval support, and I think the laggy animations startet the moment the ships arrived on the map).
Now I don't now what circumstances cause this problem but I hope CA repairs this with their next patch.
