Runegraft Of The Warp does not affect buffs given by Orichalcum Ore deposits (with proof)

In this gif, the K'tash's Anger buff (awarded by completing an Orichalum deposit) is on the far right. The other buffs are from shrines. The green outline means the effect is a buff. The blue numbers indicate those buffs are affected by Runegraft Of The Warp ("Buffs on you expire 30% slower"). You can see those blue timers decreasing noticably slower than the timer for K'tash's Anger buff.

Therefore, Orichalcum buffs aren't affected by Runegraft of the Warp even though they should be.

Thank you for your time.
