On my level the wall and ceiling are drawn like this:

There is light to be seen on the ceiling at the other side of the wall:

Now I know this can happen with dynamic lights, but with static lights and where the wall is between the two ceilings?
The light goes through the wall.
And yes the snap is on in WED, so there is space between the wall and ceiling.
Anybody an idea about this issue?

Edit: In A6 this is not happening, (this level is made with A7)
