Primary spec buttons overwriting secondary spec when zoning into or out of raids

Since today’s maintenance…
I logged in my warrior ( secondary spec was active) but the button bars were the ones for my primary spec.
Swapped spec to primary and back to secondary and the correct buttons appear.
Zone into a raid instance (molten core in this case).
Button bars revert once more to primary even though I am still in the secondary spec. Have to toggle specs to get the right buttons back.

its every loading screen it feels like…have fun

Wow. Hate it when tech tries to patch-fix one problem and creates a worse one.

And this is especially awful for casters since bliz thinks it’s a “great idea” to nuke all our mana to zero every time we swap specs… for some inane reason.
