There are some maps that have floating rocks. There is nothing a Foundry builder can do about it beyond wasting precious available objects in order to hide or fix them. I could put that console squarely on the floor, but then I don't have access to it. Yes, having a rock underneath a console looks stupid, but it is better than a floating console that I can't put on the floor or I would lose access to it.
When you are doing your review, please keep in mind that we are dealing with limited tech. Before you review, get a feel of the system so that you can take points off for author errors but don't get overly critical of Cryptic errors.
