Army levels are gone :(

[egewithin]

You may had it before, my SM army levels were gone for once, then I played them a lot and came back to 42, and this time they are gone with Chaos stats, Any solutions there?

Probably not, it's a rare but known bug, though it used to happen before the battleservers and generally in retail after playing a ranked match, I think though there's a mod to give all your armies level 60.
