This question is prompted by the iOS implementation of the game by Playdek, so it may just be a flaw in the game, but I'm just checking to make sure there isn't some rule that I'm not aware of.
Here's the scenario: "Delver's Folly" and "The Palace of Waterdeep" are in play. I already have an agent on The Palace from a previous turn. (The Palace allows you to place the Ambassador at the start of the next turn.) It's my turn and I place an agent on Delver's Folly, which then allows me to place a corruption token on any action space. I want to place the token on The Palace, but when I do so, the game pops up a message that says "You will not receive the Ambassador. Are you sure you want to take this action?" It sounds like this will negate my previous play of putting an agent on The Palace, but that doesn't make any sense to me. Is there some reason this should be the case, or is this likely a flaw in the iOS version of the game?
