My Penthouse won't allow me to place blocks in certain places.

[SwerveeSS]

When I go to place a block it certain spots. (Picture Below: Dark Oak is where I can place and the empty space is where I can't. And that's just the floor, same thing happens all the way up to the ceiling.

It's super annoying and I can't decorate the penthouse.
Hope this makes sense <3

- Please remake this thread and follow the format found here

- I've had a look at the apartment you own to and it
seems like there are a lot of areas that cannot be built over. I would
suggest that, when remaking this thread, you state that you need your
penthouse region to be completely redone, considering just how
many glitched spots there are​
