Darkglare ones cannot be learned and don’t return any kind of error.
One grimoire for Observer (stratholme) is completely missing as opposed to PTR and one random which I can’t figure out has been learned without me ever going near it. Switched specs, changed zone, relogged several times, summoned the pet, changed the demon appereance… it just doesn’t work.
Durumu skin randomly becomes available or unavailable in the barbershop and I have not obtained it yet.
Last Tyrant skin which was expected to drop from Radix in Antoran but he does not have it.
