Hello,
Sorry for the late response. I meant to revert my changeset immediately and star over, but for some reason I couldn't download the Revert Changeset plug-in to JOSM. In the meantime, real life has got in the way and I haven't been able to rectify this. I think it's still better to delete and start over; I still have a local copy of this edit. If you or anyone else wants to do it, be my guest.
