Here's what I found out and here's what I did:The error appears to be from a multipart poly with a portion that touches only by their corners (think of 2 business cards touching at the corners). I broke up the poly into 3 pieces and created a geodatabase with a dataset for staging. Via that process of creating lines & a topology, I used the 'Load a Topology to a Parcel Fabric' tool which appended that parcel into my ParcelFabric. In the fabric, I merged those polys back together.Afterwards I had 2 or 3 other parcels in different staging sets with the same problem and was able to resolve it via this same procedure.I hope this helps anyone else who may come across this type of error or something similar.
