Interesting, can you please show some examples of self-intersections from the deleted import? I think I know the author and I may help to fix these intersections programmatically before the import.

What was buggy here?

Wow, good to know, thanks! Looks like it's a bug in Organic Maps, we'll fix it.

Ok, sorry.

Hey, this is a test comment to a changeset from @deathbaba

Hi Derick! How did you change building:levels from MAPS.ME? :)
