The error someone gets when they try to change a project to a status that equals complete:
I often get asked by PMs why they can't project close their projects when all their tasks are 100% complete and all issues are closed. It's because there's at least one task that is pending approval. So the task may be 100% complete, but the status is " - Pending Approval". I suggest maybe re-wording the error to make it clear what's meant by "tasks that are not complete".
Thanks!
