Map orientation/ coordinate system

While we wait for 1.3.1 would love to fix a direction issues I am having. Am using Dynmap and Spout compass - works perfectly when I want to move - i.e map shows move in N direction and I follow compass on spout. The problem comes in when I use worldedit to expand block selections - //expand 5 n for example. It then expands 90deg off. I read somewhere that the map coordiante system changed - but cannot find a config/ master setting to align so they are all on the same system.

any suggestions appreciated?
