The auto attack was working fine until some point in the game when my hero stopped attacking when I either ordered a Attack command on the ground or when receiving any aggro effect, like being hit by a mob or standing still with Hold command. It only attacked when I clicked directly in the target. The patrol command did not work also.
I also received a message error in game warning about a crash. The replay is attached with the post. The auto attack issue can be seen in many parts of the game, but I tried to catch a moment to show cleary this, at ~~55:20 (after picking hero). In this moment, you will see Oracle in the scourge jungle attacking ogres. I clicked to attack once, then I clicked to move. The ogres will hit the hero, but the hero will not attack them. I tried disabling and enabling the auto attack (-aat), but did not solve.
