I just completed a final truth quest, turned it in, got void born core, and it won’t let me shift click to upgrade the claok with the voidborn core. Tried relogging several times including turning off addons and exiting battle net completely. Also, the Titan ic Research Archive shows I already purchased the Extreme Elimination thing, but it won’t let me buy the next one, Extreme Destablization, even though it shows I have the required currency for it. Earlier today I completed 500 cloak on alt priest, and I had to earn 4200 more mementos to REBUY Extreme Elimination. PLEASE FIX THIS.
UPDATE: Suddenly installing the core in the cape worked while standing in a pug raid in the vale the day after above post. Go figure…voila my cape finally 492.
