I'm receiving the following error upon logging into the game after updating to 9.1.5, Thanks.

Yea, sorry about that. I seem to have grabbed the wrong error when I posted. So many errors popped I grabbed one for a different addon. When i get a second I'll reload and get a fresh list of errors to find the one for Rarity. Thanks.

Found the error. It's the same LibQTip: 48 that was posted as #430. So feel free to close this ticket. Thanks.

From the patch notes:

Item Upgrade UI has been reworked.

However, Rarity does not listen to this event. What makes you think this error is caused by Rarity, @Ookami313? It appears to be an unrelated problem, so I'm not really sure what I could do to fix it.

Since the patch isn't yet live on EU servers I can't check for myself, but I see no way the unrelated Item Upgrade UI changes could possibly affect Rarity's functionality.

@Dawawe This is a separate issue; please check #430 for status updates as I research the problem (after the patch goes live here) :)

Gotcha, closing this as invalid then :)
