What you are seeing
A save appeared to succeed but the diagram is now missing from the issue entirely.
#Why it happens
On edit, the old attachment is deleted before the new one is uploaded, and an upload failure is not surfaced. A failed save can lose the original.
#What to do
Reload the issue to confirm the current state before assuming a save worked, and keep a copy of large or important diagrams. Retry the save; if it keeps failing, check that you still have permission to add attachments to that issue.
