Summary0000067: Strange AI battle behavior (enemy Pikeman fighting Ammo Cart, while the rest of the enemy stacks remain stuck midfield)
Description0.72d#09 Strange AI battle behavior: when 1 Pikeman started to 'fight' the Ammo Cart, the other 4 got stuck in the middle of the battlefield for 4-5 rounds:

To reproduce, load the "Spell Learning" map attached to the post on the forum (above the report) and attack Pink hero (Tyris) with Sir Mullich. What I did was to use Defend for all my creatures continuously and shoot only with Ballista. One Pikeman got to my Phoenix and was killed in retaliation, but after another started 'fighting' the Ammo Cart, the others remained frozen for the next (about) 4 rounds, until my Ballista finally killed the Pikeman in front of Ammo Cart. Then they started advancing again. A couple were killed by Phoenix retaliations, but when after a 3rd Pikeman 'got angry' on my Ammo Cart again, the 4th one remained again stuck for a few rounds (until my Ballista killed the one next to the Cart):

In wog with extended war machines units also attacks war machines frequently regardless of armies (but they not stuck)

Well, in WoG it make sense, because there War Machines are actually worth something.

But the main problem is not that a pikeman started to fight with my Ammo Cart, but that all others remained stuck until I killed that pikeman. It was like killing the Ammo Cart was their only objective in battle (but even then they were not very smart, as one or two of them remained stuck in a position that kept the Ammo Cart out of their walking range).

Not an issue anymore, following the new battle AI changes implemented in 0.84 (using the same steps to reproduce, the Pikemen didn't even touch my Ammo Cart anymore, but they all went to attack different creatures in my army, albeit with a preference for the Phoenix, which eventually got them all killed in Phoenix's retaliation).
