There's no sign of the patch yet, and we haven't heard anything about it either :). As soon as any information appears, I assure you that someone will definitely publish it in the News section – if not me, then someone else. For now, there is an opportunity to play the TE mod. You can find information about it and a link in this topic. If its changes appeal to you, of course.
To be honest, I am also upset about this bug :(. Partly because of it, my desire to play as the Alliance is somewhat diminished (but not completely gone). However, I haven't really tried developing a powerful Chaos faction yet. By the way, if you collect two items from Sar-Iss’s regalia (they double the magical power of all Sorceresses in the army), will the magic passed on by the Druids also be doubled? Or are there some nuances?
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
