Wetlands

Posted by eric22 on 18 November 2013 in English.

If I didn’t hate wetlands enough because they were mosquito-infested swamps of no use to human beings, I would hate them because of how much extra work they cause when they get imported to OSM.

Sorry environmentalists :)

I was just looking around at some of the errors and found some edits by the redaction bot. I wonder if it played a role in that particular disaster.

Those objects were also touched by the redaction account. I remember wierd stuff like that happening due to ways being split by non-agreeing users then those entire segments being redacted. This looks like compounding data issues with imports and redaction.
