K curve seems to be calculated incorrectly from soil properties #5806

It appears that SWIM3 can create Ks(psi) curves that are incorrect. See summary file for deeper layers. Ks in model is > Ks in inputs. Soil Hydraulic Conductivity

Is is using hyprops? I implemented that for WEIRDO so if it is using the same code there could be a bug

When updating and using the provided apsim file, the bug is still occuring.
