Ah I see, I must have missed a few of those when I was looking at the buildings. 
So I downloaded the Microsoft Building footprints for the entire state and split out the file into counties, from there I downloaded a layer of all the current buildings, and then in QGIS I ran some geoprocessing so wouldn't duplicate what already existed - this is where the tiny slithers and segments came into it. I apologise for missing those. I also was not meant to have the edit related to this account, it should have been my person account. 
I can add in a step to avoid this in future, I can also assess this changeset and the one you mentioned. Unless you are willing to share the detections, in which case I would be more than happy to look through them so you don't have to correct my edits. 
Thank you for catching this, I really appreciate you taking the time to respond.
