House customization problem

[Frito Figmus]

hi all, when i go to commit in the menu i get the message illegal floor! . i have no orange tiles or anything bad like that, but cant seem to get this house to go through. anyone know what this could be ?

There's a bad floor tile. Try going floor by floor and making the walls transparent/invisible. Fucky floor tiles always hiding behind walls/steps.

this always gets me when making a big house design too ^_^
