I just finised the duality dungeon solo for the first time, but i didnt get the "Solo Thoughtstealer" triumph under the "Duality" seal. I completed it over the course of a couple of days due to limited time. My question is do u have to complete the entire dungeon in one sitting in order for it to pop? If thats the case then why are u able to complete triumphs completing master raids utilizing checkpoints, but it doesnt count if u do the exact same thing for a solo dungeon completion? Doesnt make any sense.
