I would say the problem with the AI not putting in concentrated attacks has been fixed Pete! Take a look at this screenshot of two very powerful attacks going in on the morning of Day 3. Even better, when the attack on Tirnavos fails because I managed to insert my mobile reserve into the town, the AI withdraws, reforms and attacks again the next morning, with another two very powerful attacks into my soft flanks and attempts to encircle me! Excellent tactics by the AI. I'll post the screenshot from the morning of day 4 later.
