Aww you beat me to it...but that's okay. I haven't edited any parts as of yet.
I don't have access to Edger2 (I use the eeevil Mac platform). But as you've started editing them, the following pictures may help you identify the overlap in 2998.
Just look for where it isn't smooth.
Maybe it would help if Edger2 implemented a feature that flagged any two points were >0.01 u and <(minimum part edge length) from each other. Though I 'spose I could write up my own parser that could identify such an issue if it would help.
