If you have a Prayer enabled, eg Piety, then toggle Quick-prayers (which disables the prayer), Prayer#isActivated remains true.

I imagine this is because the InterfaceComponent needs to be visible in order for the API to detect a change in state, as opening the Prayer tab correctly changes the state of the Prayer.

Slash, might be an idea to revert to Varps for isActivated() (if they were used previously, if not, now might be a good time to make it happen).
 
Worth mentioning that on OSRS (not sure about RS3) interfaces cannot be accurately queried unless they are visible, so it is a really bad way of telling whether or not a prayer is active.
