School Desks Known Issues
I don't know how Orphans of the Commonwealth works, but some of my child settlers are slightly different sizes, which may make them clip a little. I used setscale to make the size of those settlers a tiny bit bigger, it's only a visual thing, but it bugged me. See the image with the three children in the vault to see the sort of clipping I mean.
For some reason when looking through a vault door at the chalkboards they flicker a little, but looking at them sideways or from a distance is fine. Possibly this will happen when looking at them through other things as well. This sort of thing can happen with unedited vanilla meshes as well. I've seen nearly every item in a room vanish when looking in through a gap in the wall.
