The value for Easy was to high it should have been 106 instead of 110 in the past. Since nobody was able to built a Fullbuild on Easy with 110 the values for Medium and Hard where lowered too. Fullbuild should now be possible on Easy.
Short summary: Open the mapeditor, create your path, doublecheck the pathing/blocked coordinates/empty lines of code/mapauthor signiture, create your background (respect the copyright | don't steal), make a mapfile, make a zip, upload your map in the forum, play it ingame.
