Hello,

due to a bug in the software, nodes that have the same id modulus 2^64, have been confused by the software.

You can reproduce the bug (on a worldwide instance) with a request like

http://overpass-api.de/api/interpreter?data=[out:json];(node(1);node(4294967297););out;

It should show two different nodes. If you see only one of the two nodes or no node at all, you are likely affected by the bug.

There is a fix available in the minor_issues branch. Unfortunately, you need to reload the database afterwards, because the bug has made various nodes disappear. The clone endpoint, available at

http://dev.overpass-api.de/clone/
resp.
--source=http://dev.overpass-api.de/api_drolbr/

has already been fixed and can be used to get over the bug after the software update.

I'm sorry for the inconveniences. A thank you to mmd and tyrasd who have reported the bug.

Best regards,

Roland
