FDDNM "MUST" be built locally.
Please see: http://www.freedroid.org/doxygen/tools/fddnm.html
in FD doxygen page for instructions to build.

Note dialog node actions/behaviour has been made more complex with Dev's writing
more involved code for user actions. This makes a rendering tool such as FDNNM
difficult to maintain.

I will verify fault and if possible offer a fix, but no promises.
