A big part of the problem is that while not everyone does this, a large amount of players use macros or bots for 20 plus hours on houses.

No player in their right mind is going to stand there for 20 plus hours manually clicking on the plaque when competing against someone who is likely running a bot clicking that same plaque every 2 seconds.

Other than periodically checking for non camped houses in the middle of the night, I'm waiting for this system to change. It's embarrassing for a AAA company to have a ridiculous system like this.
