Good report but for me it happened with a Rook and a Regulus.
REPORT #2 :
I just left a game where I was allied with 2 Torchbearers. When I reached level 20, one of them decided to park himself in the rear, at the structure where we heal our wounds : he NEVER moved from there until the bitter end (He wasn't even facing towards the enemy) !?! And then, when I reached level 24, my other ally also decided to remain in the back, stationary (He, at least, was facing the invading enemy and casting spells).
Well, of course, the enemy Rooks pressed their major assault against our base, and "we" lost.
If it is a problem with A.I. coding, why does it seem to more often affect my ally comps, and not the enemy A.I.s ?!?
(But it is perhaps a random, irregular « bug » that sometimes affect one side's comps, and on other occasions, affects the other side's comps. My victory, earlier this morning, was perhaps due to the fact that is was then my enemy comps' turn to be AFK.)
