Currently, without some honestly hacky code that conflicts with hover-over examining and other features, there isn't a way to detect clicking on tiles that the player cannot see. I think a sane way to do this is that for

it will pass the object as null, the location as null, and control normally, and params normally. A good way to prevent previous games from runtiming to introducing a feature would be to either make it a skin option or adding some variable option in world to allow for mouse events to register this way.
