Disciple of the Ring activations have stopped working

Ever since the update, Disciple of the Ring has stopped working. She definitely worked before. Now what happens is:
* She activates three gems successfully.
* When you match one of those gems, nothing at all happens as a result.

It doesn't seem to depend on anything else, I've 100% never seen it work since the update.

A bit of a shame because as a 7/8 vanilla for 20 mana she's a pretty worthless mythic.
