k, just did a t8 Tak-Rethan Abyss and my vault does show a T8 vault slot (1sts slot)
So 2 t8’s and a load of open world stuffs to get keys and I get a 1 tier 8 vault and slot 2 shows t1 but says do more delves to get better lootz so yea, I was wrong about it being broke and I just had to do moar 
Glad it wasn’t borke
Guess im lucky
Oh i totally agree and in the endless pursuit of better gear ill probably get around to it at some point its just annoying
Was that an older video, I think for a bit pre-launch it was 12 for the last slot, but you should only need to do 8 tier 8s to get all three to that.
Basically just the lowest level tier you’ve done of the highest 2/4/8 runs, so if you did say 2 8s, 2 7s, 2 6s, and 2 5s you’d have tier eight loot in the 1st slot, 7 in the 2nd slot, and 5 in the 3rd slot.
