I have an interesting problem. A user with admin rights accidentally changed a couple of statuses for all projects using the simplified workflow to a custom status they created.
For example, every issue that was assigned the status of "Done", now has the status of "Win", across every active project (about 80 projects). Unfortunately, they don't recall what they did to get to that point and I can not figure out how to undo this. Note the issues are actually assigned the status, it's not just an additional status.

What's odd, is it only seemed to affect active projects. If i create a new project, it uses the correct, default statuses in the simplified workflow.
