Heroes of Might & Magic III: Horn of the Abyss

Will old bugs from the SoD era be fixed, such as increased damage dealt by city towers to a unit affected by the "Air Shield" spell, capturing blocked cities using the "Fly" spell, and others? Also, there are some issues related to the unicorn aura. Some believe that it doesn't work for upgraded unicorns.
It would be interesting to see the implementation of unused animations for old creatures (Hex-Attack).
