Hi,
A couple of issues with Tabrabucca Farmstay 17449614 multipolygon relation;
tourism=chalet is a single building.. not a farm... 
multipolygon relations roles are either 'inner' or 'outer' not 'member'... 

The 'chalet' Way: 1276733648 appears to be the main homestead for the farm so should be tagged building=farm name=Tabrabucca 
Source=DCS Base Map

The Way: 1276733649 tagged     "building"="yes"   "tourism"="chalet"

looks to be the farmstay and should have the relevant tags for that feature.
