I recently created a raised platform in one of my husbands houses, which is the township courthouse. I created the platform for the judge, no problem. It is 1/4 wall height was working just fine. Now you cannot walk on it. There werr floor tiles above it when I could walk on it (and there still is floor tile there). Is this something new, or was I never supposed to be able to walk on it? I know that on the platform I created that is 1/2 wall height (the 2nd row of the juror box) you cannot walk on it with floor tile above. This is also happening if I leave the flooring off the floor above and just place walls and a high roof. Once the roof is on there you can no longer walk on it.
