The building footprints that you added are valid and appropriately squared. You made an error when mapping the crucifix shaped building WAY: 1327091573. This resulted in the landuse area and building sharing common nodes and this seems to have also 'knocked' the building footprint out of square. Hold Alt to prevent your cursor from snapping to other features. You can also filter out data via the map data panel. Landuse areas should not share common nodes with buildings. Thank you for your contribution.
