I placed a Keep back in December. Someone owned an 18x18 behind it which fell just a couple of weeks ago and I decided to move my 18x18 storage house so that it occupied the recently vacated spot. I just noticed that my Keep is now "improperly placed". I have never owned an improperly placed house before so I had some questions. Doing some reading it looks like being improperly placed doesn't really affect anything unless I try to demolish and replace the Keep in future, in which case it wouldn't work (possibly for resizing but I can think of no other reason). Are there any other drawbacks to being improperly placed? Why would placing a legal house behind another cause one of them to be considered improperly placed? Shouldn't the placement rules keep this from happening?
