Ungauged node: difference of ErrorCrit between Calibration and RunModel

How to reproduce:

  • Calibrate a little network with at least one ungauged node
  • Run the model after calibration
  • Compute the same ErrorCrit as the one used for Calibration
  • Compare the value of the ErrorCrit of the downstream donor node: they are different

This issue is not arising on this configuration:
