Window/door placement in wall on uneditable design option

[thesleepofreason]

Currently it is possible to place door/window on a wall that is on an uneditable design option. The window/door becomes uneditable after placement so it seem to be a bug or inconsistency.

So,  when the 'Edit default only' option is on.

Yes, it seems you can add doors and windows still but not edit them or the other elements in that option.

I agree, technically you should not be able to add a door or window as that is editing the wall that you have said to not be editable.
