I've removed the empty polygons.

Regarding relation 14442220, I didnt create it that way, but I cleaned it up by separating it into two separate relations.

The old polygon was not very accurate. New geometry required a hole in the wood polygon. Inner members are the best way to do this.

Thanks guys for noticing these issues.
