This was a problem in WaterGAP 2.2e and needs to be checked for ReWaterGAP. It might be introduced also in ReWaterGAP due to loading a saved state. See issue 268 and issue 279. The assumption is that in an uninterrupted run the pc can calculate with a higher precision than the values are saved in a file and due to that small diffrences can grow bigger the longer the model runs.
