my map shows the orange circle covering a diameter of maybe 10m.
Don't think that is what you want, even the playground southeast of here is larger.
Hang on, I just zoomed in for more detail and it's about 5 metres across.
What is wrong with what Constable did for you earlier today?
If your work was deleted it is likely that it was too poorly done, not meeting OpenStreetMap standards of accuracy and ground truth.
Be aware that due to a large amount of abuse of OSM over the last months, such things are viewed with distrust due to the damaging behaviour of a small handful of abusers.
By the way, you are likely to get better coöperation without SCREAMING YOUR HEAD OFF, or being overly dramatic about the importance, as there are a lot more life-critical things that are given priority here.
