Are we all done with the challenges or is maproulette broken at the moment? I can’t get it to load any further tasks.

@Katie U: I’ve encountered lots of those in MA where they seem to come from an import. I usually simplify those ways (NOT using JOSM’s default setting, as its way too coarse) and then manually confirm that things look good. Usually I have to add in a few nodes again.

Another observation: Some of the ways I came across had 5 or more changes in the last few days, presumably all related to the roulette. How many times does a task get assigned before it is marked as fixed?

Nice challenge. I noticed that there are a lot of false-positives with highway off- and on-ramps. Maybe it would make sense to filter those out for the remaining 90000?

Thanks for organizing, it was a lot of fun!
