In my Romani campaign I have to fight a battle south of Alexandria to save my Ptolemaic ally from Seleucid invaders. However, after deployin my forces, right in the moment when i start battle and the other parties' troops appear, the game freezes. Note that on the battlefield should appear also 2 smaller Ptolemaic armies encircling the Seleucids, and note also that quite a large part of the battlefield is covered by sea.
SO does the game freeze because my ally's troops would be deployed in water, which is obviously impossible and therefore crashes game?
