Fill Sinks crashing

Question

I am using for the first time the deranged basin workflow in ArcHydro in ArcGIS 10.3. All goes well with the DEM preconditioning, I successfully defined sink polygons with larger ones set to IsSink =1. But when I execute Fill Sinks, it runs for a while but ultimately end with a (typically) undecipherable error message.  Tried closing and reopening the proejct. Same result.  Any suggestions besides upgrading to 10.4 (which I'm willing to do, just something I've been putting off)

I've discovered that my SinkPoly grid is not recognized in the Data Management window as being a valid sink polygon (i.e. I can't assign that layer in the data management window).

I can fill sinks if I do not use the deranged polygon option (the layer that is somehow invalid) but then when I try to adjust flow direction with sinks I cannot select the sink polygon layer.

Any ideas?

I have executed many successful workflows with my current setup. It was only when I began creating sink polygons for a deranged basin that I ran into this problem. I think my setup is fine.

You're right, that is undecipherable!
