Hi,

Relation 15577991 does not make sense? natural=wood;heath err no. It is either heath or wood. And both members are 'outers' yet one is inside the other. 
Looks to me like way 1152292927 should be tagged natural=wood (as it was before this changeset) and then have the role 'inner' in the relation. The relation should be tagged natural=heath

See what you think.
