I have a small suggestion for these Coin Exploration events we have from time to time, like right now with the Love Houses. From what I see, it's a problem when people explore the locations and leave the marauders behind.
I suggest the coins should only drop as kingdom events when the marauders are killed, not before.
New players wouldn't end up getting killed in a small neutral city by very large marauder armies or people wouldn't lose heroes in their own cities because someone explored the location and left the marauders behind.
