Yes and No. I see them since a very long time, and I think
I saw them the first time when rounding in mkgmap was changed to fix
routing across tiles.
But since some time I see them only very seldom, so it could be
very well that the change had nothing to do with this, only
I haven't really noticed it before.

Did never had the time to really check if my observation is really true.
But I got several reports, that this "errors" are very prominent visible
on some maps on nearly invisible on other maps. But even that didn't lead
me to any new idea.
