At my brother's wiiu last night after purchasing 2 new create-a-soldier-squadmember slots the Operations menu seems not to work anymore i.e. does not show the screen with the operation categories.
Menu path: Multiplayer ==> Ghost online ==> Operations leads back to the Multiplayer menu
Menu path: Multiplayer ==> Ghost online ==> Find Match => Operations leads back to the Ghost online menu
So instead of the operations categories screen it seems to jump to one menu level higher.
