This is similar to what I am getting on the Northeast France Map.
I think it is due to map_h not map_c.
I have been successful in smoothing out some areas but still have a lot to do.

Problems occur because of the difference in pixels between map_h and map_c
Some areas you can see an obvious shift in the pixel position on map_c and can correct it by editing map_c.

In other areas it has been necessary to lower map_h by a small amount to get it to look right.

However I still have a lot of this sort of flaw to correct so I will be watching this thread with interest for other comments.
