You've undone a lot of work with the mistakes you've made in this edit. May I suggest some things to you? Focus on making smaller changes, work on one smaller logical change, then save it. It's very hard for a human to keep so many things in progress in their head all at once without making mistakes, which you do. Instead of spending time making sure there are 100 nodes for every curve of every flower bed to make sure it is super smooth, devote that time to making sure your edit are correct. Other editors spend a lot time to get thing right, including going out and recording with multiple gps units to make sure features that do not appear yet on any aerial imagery is correct. So it is very disheartening to see that work destroyed with your huge edits. Just think that the reason a feature is where it is, or has a certain tag might have been very well thought through and considered more than the time you have devoted to it. Don't rely just on aerial imagery, the edits made may have been done based on in person visit and conditions might have changed on the ground or be hard to see in the aerial imagery.

Some specifics:
You've moved/shortened sidewalks that I know (and verified) to be gps accurate. You've changed path surfaces that I know to be accurate. You've deleted paths I know to exist to this very day. You've deleted a sidewalk that was created last year that is not on the aerial imagery yet, I went out and manually mapped it using gps so the map would be correct. If something doesn't match the aerial imagery please consider that it might be more up to date then the aerial imagery. You can check the edit that put it there to see the date, and what source they used for it.

It wastes both your time and other mapprs time when this happens, and decreases the quality of the map if not caught. Please consider the damage that you are doing before your next edit.
