When doing the final growth of true clumps, NoiseChisel currently uses 4-connectivity to expand the clumps. However, we have defined the detections using 8-connectivity.

As a result, I just found some rare cases where the detection had an 8-connected region to the main body with no true clump in it. As a result, it was left unlabeled after the final growth and would somehow get a wrong label (similar to another object in a completely separate part of the image).

I am now working on the fix...
