As seen in the wind vector hedgehogs in the first and second visualisations, sometimes the AVS 5 hedgehog module will, for unknown reasons, not properly colour the vector field, despite having all the appropriate parts of the network required for this. This problem was unresolved, as the length of the arrows show their magnitude, and while it would have been nice to have the arrows coloured according to their magnitude, the length is (barely) good enough.
