Whispering Felflame Crystal dropping again

It looks like a hotfix was just pushed. I got a crystal last week on my paladin as expected. After the reset, I wasn't getting another one. Just now, on my 4th timewalking run since Tuesday, I got another crystal.

So I think they must have made a change which will mean that we'll be able to at least get a felflame crystal each week for the duration of the legion timewalking. Rejoice! I'm really hoping this will extend to the 5 run weekly quest as well.
