I hate when I go start a auto trade route and leave my computer for like a hour and when I come back to check on the game all my gold is gone because I got plunder and there is no way for me to store my gold. So a answer might be making a bank page not to complicated just put it some where like under the court page. It could be used to store gold for players who dont play 24/7 and cant watch their ships and trade routes
. There could also be a intrest of like 1.2% every 2-6 hours . Also so people dont go and put all of their money in the bank which would stop the need for plundering there should be a fee to put money in the bank like half of the sum that you are putting in the bank. Or something like that this would be an amazing feature to the game and very help full .
