Yep. Still an issue. Btw, my response was in relation to when one of your companions/family has a party in your army. Not sure it workss with unrelated parties as I don't generally donate to them.
It also happens with parties within your army that are from other clans. I just liberated an entire garrison from a massive Khuzait army, like 500+ troops on top of my already full party. When trying to divide up the cannon fodder troops I encountered this bug trying to "donate troops to party" of any party within your army, including your clan and AI clans.
I am able to inspect my clan members party through dialogue and distribute troops (though I'm not sure if that's through one of the mods I have). For AI clans the "done" button greys out and says "too many prisoners". I am running version 1.02 though.
