Hello,

There were already two address points inside this building.

We never write the addresses on building outlines when there are several addresses.

I tested in SCEE to reproduce the problem: it is possible to force address duplication with the Places layer… but it will show the existing address points anyway.  Should you come across similar situations in the future, I suggest you ignore the quest entirely.  This will avoid data corruption in the database.

Thanks for your cooperation.
