Batch keeps disappearing

Andrew, Leslie Victoria

Does anyone know why the US Massachusetts Boston Tax Records 1822-1918 Part Y keeps disappearing? I was indexing a couple of weekends ago, and then it was gone. Showed up again this last weekend, and now it's gone again. It was only at about 17% done

If it was almost complete, and no batches are available to index or review, it won't show up in the Find a Project list. Then when batches become available again because they are returned, it shows up again.
