Comment # 1 on bug 980962 from Arvin Schnell

Unfortunately the report is not entirely clear to me.

"reports snapshot 475 as the current snapshot. Upon inspection of the actual
file content, snapshot 489 is indeed mounted as current."

While doing so you booted the default subvolume and did also not change the
default subvolume (e.g. via a rollback)?

How did you do the inspection?
