some information was lost here, before we had address 86B and then address 2/68 but you've replaced both with just 68B.

If you're not sure which applies to what best to leave the two address nodes as they are and only move the building=yes tag along to the building. I've fixed this up. If you're just working remotely probably best to leave the addresses and just change the building=yes tag from the node to the new way.
