And my colleague's house is from 1605 rather than 1005. It's not quite Y2K, but it's interesting that the last two digits seem to have survived whatever error occured.

Maybe some other bugs too... There's a capital L shaped area that is marked as all 1995-2005 but when I click on it, it alternates between:

- 1738 - Vijfharingenstraat 5 6211EC Maastricht

- 2002 - Grote Staat 5 6211CT Maastricht
