This didn't work, because the Add and Density brush now require a uv map on the surface that can be used to store attachment information. In your case you can recreate the uv map so that there are no overlapping islands. Or you can create a separate uv map just for the surface attachment.

I added a warning, so that this doesn't fail silently anymore.
