Hey Blake, your description of the bug is exactly right. We’ve made a few improvements (like introducing a delay to the save), but it can still happen sometimes. We’re tracking this issue here: https://github.com/openstreetmap/iD/issues/1646 <https://github.com/openstreetmap/iD/issues/1646>
The telltale signature is when you see a person add a bunch of things, and then that same person adds them again a few minutes later (because they did not show up post save). If you see multiple people adding the same things, that’s not an iD issue - that’s just multiple people editing in the same location, which we can’t do anything about..
