This error doesn't seem to be or cause any real problems, though it does come appear when I log in or reload UI. The problem is the addon has no information about Fury of the Illidari ability. This also happens with my mage and the same issue with her artifact ability, Phoenix Flames (ID#: 194466), thats the only other character I've tested with. I do have LibArtifactData and LibPlayerData installed and updated, even tried the alpha release of them but to no avail. Am I doing something wrong? Thanks in advance!

Ah you're right, I had a faulty script active I forgot to delete. And thanks, I didn't realize it was AURA based, which I should have gathered from the title of the addon haha. I mainly use this to light up my buttons when something comes off cooldown since there are a lot of short cd's as a DH and the only thing that didnt work was Fury, so oh well.

However, for some reason now im getting this error:

The artifact tree window also auto-opens upon login and reload. I used to have the same problem with Exorsus Raid Tools but disabled it, now its happening here. (I disabled AdiButtonAuras and the problem went away.) Should I post in a new thread?

Yes please, open a new issue for the last problem. Btw it does not happen for me, so exact steps to reproduce it would be nice. Also a list of your addons would be much appreciated, if you could get one easily.

First about the error report:
114866 is the spell id of Soul Reaper, which was removed in Legion. Please check your custom rules and disable/delete/update any of them that contain it. You maybe accidentally enabled our sample rule, which is outdated and that is causing the error.

About Fury of the Illidari:
LibPlayerSpells (LPS) actually has the ID, however there aren't any associated auras to it. Since ABA is an aura duration display, I'm not sure what you expect it to show/know about Fury of the Illidari.

Same for Phoenix's Flames. If it does not apply a (de)buff, then ABA does not care about it.
