Bruteforce resigns mid game even if IT has the advantage in battle and map control on. (Hardest difficulty). I had no problems playing the following compositions: (Hardest difficulty)

1. 4 vs 1
2. 5 vs 1 and 5 vs 2
3. 6 vs 2
4. 5 vs 3 ( this was amazing, I slept dead after this match)

BUT when I am trying to 3 vs 1, 2 vs 1, IT simply resigns after some time.

Any idea of Its behaviour?
