Certain decorations can be placed on the invisible ceiling in the aquatic HC

When decorating an aquatic homecave, some decorations can be placed directly on the invisible ceiling. They do not require a solid surface or walls, resulting in levitating decorations. Note that this bug does not affect all decoration items, only specific ones.

Certain decorations bypass surface requirements and can be placed on the virtual ceiling without any physical support, causing them to float

Decorations in the aquatic homecave should require a solid collision surface for placement and should not be placeable on the invisible ceiling
