I have noticed that I can't build more than 3 caravans no matter what I do. It says to research diplomacy and I have that all the way to the point of just doing it for cheaper recruiting. Nothing is improving it. Do I need a specific building built more than one or something. I can't figure it out. None of my cities can go past three caravans each.
Also I can't for the life of me delete a ship once it no longer serves a purpose. It pops up the message saying it will join the population of the nearest settlement but it doesn't. It stays on the map and won't disappear and I can continue using it after it was supposed to have been disbanded. I don't get it. It won't delete. And the only reason why I continue to use it is because i have no choice. The only other option is to fortify it but if I don't need I don't need it and would like to delete it.
Please fix these two issues or if there is something I need to do to get access to more caravans please let me know.
