What did you do?

I renamed an already published dataset and tried to push it afterwards (without success):

$ qri rename mfdz/destatis_unfallorte mfdz/destatis_unfallatlas
renamed dataset to destatis_unfallatlas
$ qri push mfdz/destatis_unfallatlas
remote response: 400 this dataset has already been published

What happened?

Can't neither push the dataset (see above).

In qri.cloud, neither searching for the new nor the old name yields a result: https://qri.cloud/mfdz/destatis_unfallorte returns Lost blob alert https://qri.cloud/mfdz/destatis_unfallatlas returns 500 - {"meta":{"code":500,"error":"reference not found"}} (though https://qri.cloud/search?q=unfallatlas) returns the dataset as search result. The dataset is not listed as an mfdz associated dataset on https://qri.cloud/mfdz/
