Cannot use command skills while shapeshifted

As the title says, you cannot use command skills while shapeshifted. This means that if you take the keystone that allows your to use a scepter and talisman you will never be able to use a command skill while in your shapeshifted (talisman and scepter holding) weapon set. The minion will be unsummoned due to not having enough spirit or intelligence in the non-scepter weapon set that you are forced into. Deactivating the minion or command skill in the other weapon set does not work.
