Defend the Oppressed (Conquest Mode Challenge - Clan of the Bear)

I would like to report an issue that prevents to finish the Bear Clan conquest: the challenge Defend the Oppressed.
The problem is that the mission becomes impossible to complete because, before the end of the year 801, the enemies launch an enormous combined attack: each enemy will have, in addition to their leader, at least 6 soldiers.
Since the enemies attack the same territory together, you need to be prepared to defend against an attack of 14 troops right after the first winter ends!
I can understand if this level of difficulty were present in more challenging modes, but NOT in easy mode...
The worst part is that, even if you manage to defend the territory, you will be immediately attacked again by enemies with armies consisting of a leader and 13 soldiers each.
I waited for the January 16, 2025 update, hoping the issue would be resolved, but nothing has changed.
