Possible issues with files form wharf closed
It seems that there may be issues with files uploaded from wharf, most likely these issues only occur if one reuses the same name through the wharf for different data (upload and delete/move away and the upload more to the same path name).
For the moment we recommend only uploading through wharf and performing data management when logged in to bianca proper. We also recommend not uploading multiple times using the same pathname (assuming it has been moved away/deleted).
Final ticket report
We have launched a rebuilt solution for the wharf that we hope and believe will behave better.
