A turbine is causing an issue because it is positioned directly on the diagonal of the four grid points, leading to a failure in the interpolation routine. The error message provides the local coordinates of the problematic turbine, with x_local listed first and y_local following. Locate the turbine mentioned in the error message and adjust either the x or y coordinate by 1 or 2 meters. After making this adjustment, rerun the Objects module with the modified location, and the issue should be resolved.
