Maybe a noob problem ... who knows
I have this with the three target cities from the Dangerous Neighbours quest, from Lord Warren.
I prep an army, send it there with my hero. Enter quest, solo, select units and make sure there is no overstock on the army, notr on the troops entering the quest. I click enter ... Nothing happens, but the troops sent in are not in the army anymore. Relogging helps me to find them back.
Anyone went through this / resolved it ?
