Getting the same error on characters and/or specs that do not have all three relics in place; the null reference exception is likely due to this (just a guess though since I have no insight to the code base).
I’m working on an update with fixes for characters who don’t have all 3 relics yet – causing a little trouble for the crucible code.
Also, the Armory still does not have crucible data… so it is clearing it when you load from the armory after our addon and causing some trouble – working on that as well.
