Hello there,

if you take a look at The Map at this location you will find, that some other user added a shed some time after you deleted it.

You see, we map what's there (with some small but important exceptions). We do not delete objects just because "the public" isn't supposed to use it. What you should do in such a case is set the proper access tag, like "access=private". 

Please do not delete the new shed.

You will find more detailed explanations in the wiki and the community is always there in case of questions. Please reach out, if there are any.
