I am sending troops to a tribe member who may be nobled before my troops arrive. What will happen to them? Can I call them back? Will they support my enemy? Will they vanish into the void?
If you troops land after your tribe member is nobled then they will be in the village for the new owner. You would have to recall them asap. Many times as a player if I saw support coming in I would arrange my tribe to attack the village killing the support troops then telling them know of the villages that the support came from and how much (easy noble targets).
