Sub query broken in a single draft after view was edited
After a view was edited the sub query in a draft is broken. When opened it prompted the "sub query incomplete" error and the sub query join was missing the field. When the sub query was fixed, no data was being pulled from the sub query. After the draft is saved, the sub query is rebroken.
The same sub query is working correctly in other reports so it is not a direct problem with it.
When I edit the report this draft was created from, everything is working correctly.
