@mspiegelaar in a word...aargh! Yes I do I've got a cross shaped ceiling. I also get gaps around the floor. I've given up trying to add a ceiling to my castle tower. I found a bug report here:
If you want to go to page 1 and click Me Too on the first post on the thread and add a reply if you'd like to do so you should be prompted with a bug report form to fill in. Any questions just ask.
I'm adding my bug report to it later when I've taken images of my holey tower ceiling!
