Hello, this is my first post here. Actually I was gonna plan to post here in user diary to introducing my country. So the question is, how do I delete things that already uploaded in OGF inside JOSM? I’ve tried to delete roads in JOSM but it doesn’t disappearing and I’ve waited for days but it doesn’t goes off, except when you delete it on the browser editor, which is very time wasting.

I want to delete my city that I’ve been made for a few months, I feel unsatisfied with my city layout turns out and I have been very wrong since the beginning. I wanna start again from the beginning. So what do you think?
