AoV (VA) Manic blueprints

Can we get Manic AoV Blueprints for sale from Yumi? Why were they removed in the first place?
If it was to frustrate players, you sure did a good job. I am 400 runs in and have never dropped a Chest 1 or Blueprint 1 for Chest. 400. I don't find this rng entertaining at all, and as further content has come and more is nearing, people need those, so could you please add them? It's already been a fair amount of time since the dungeon came out so whatever reason there was at first should be gone by now anyway. Help those of us not blessed with luck participate in the game, thanks.

threea I hate doing this to staff for no justified reason, but can we get a confirmation on the subject either here or (maybe better) in the main game feedback thread?
