Maven 10 way invitation not unlocking scarab slot

Hi, I've been trying to unlock the fifth scarab slot. Have done the 10 way invitation multiple times with no success.

Saw a misplaced thread under in the forum about the same thing.

Did /bug on the affected character: 3 612 376 152.


Thanks!

It is a typo, you are supposed to do t17 map and not maven invitation
