Multiple cache views are activated (Ionic Beta.14)

Hi guys,

I have a trouble in cache view, when I accessed directly to a link, sometimes the link will be frozen, because there are multiple ion-nav-view are activated.

My app has 3-layered navigators, so sometimes it is complex to use ionic.

My app is hosted in here, If you access the specific link like this: http://friendshop.tidal.ninja/#/tab/explore/promotions
you will find it is frozen and you can find some other cache views are activated. However, if you click the other menu button and return previous frozen view, this bug will disappear.

Could anyone help me look this issue? Very thanks.
