I just wanted to share something.
My event roll macro has come back true almost every day since hitting AR 4
but i've only gotten 3 screeches in the week or so since the first.
I have touched all 3 stones and gotten the buff for each. Afterwards I checked quest dump and they each came back true.
I checked quest dump macros again today and everything is False except the daily event roll (true). Seems the game does not recognize me touching any stones, nor have I gotten a screech today (yet again).
Good luck!!
