Дегустация Horn of the Abyss

In HotA, these AI algorithms haven't changed. I personally saw a moment on a stream where huts didn't attack a single nymph; I can't say why this happened. For now, I don't see any obvious reasons why a single-unit stack wouldn't engage a single target, especially a weak one. Perhaps it's due to some calculation errors regarding unit value, similar to those that cause 2-unit creatures not to attack a target that's directly blocked by a wall of fire. It's also possible that this peculiarity is more common with certain HotA units.
If it turns out that the reason is indeed related to the HotA modifications, then it's a bug that will be fixed if we can understand what's going on.
