AI problem

I played recent version of VCMI(0.97, with homm3 complete), and found that AI was too easy. I tried to find out the reason by playing a map that I can be a team with AI so I can see what he’s doing. Until about 3 days it seemed to have no problem at all, but soon AI continued to attack on a strong neutral monster(like minotaur). Even if heroes die, AI recruited another hero and do the same thing. I think it’s a matter of adventure AI. Maybe it can be fixed by adding a function which compares strength between AI and monster.
Without this problem, I think we can enjoy complete homm3 with android devices.
