@ohzuna - I looked into changing up the lot on stilts and found that once those wooden stilts are placed and saved, they will never delete. No adding new foundation over them and deleting that, no using debug enabled to purge the area, no MOO or CFE tricks will work other than camouflaging them. One easy fix might be simply deleting the football from the one bedroom (which is why moving them onto a houseboat worked for you as you didn't take their household items with them). So, moving them and deleting the lot is the only fix.
The Medina household I've played before and rechecked today. I do not have a problem swimming in any of the pools, mixing drinks at the outside bar, or watching television inside sitting on the couch downstairs or standing upstairs. (I don't know why I didn't add another couch up there!) I loaded both the IP only and other version, so maybe you have the wrong family in mind, OR something in my upload was replaced in your version and that is causing issues. ((I used a ground light that could be a routing issue if replaced with another one in front of the bar.))
