[How to solve the Kuva Bramma ammo problem]

how to solve a problem?
No way. The developer specifically made the weapon unplayable. So unplayable that it makes no sense even to play warframe.

Because the developer has taken the course. Consistently and methodically remove the most popular content from the game so that players pay more donations while pumping other weapons.

And everything will be repeated. Players will have a new popular weapon, SJW will appear, who will complain about the bright special effects. The developer will ruin this weapon in the same way as it ruined the brahma, and everyone will run in a circle, pumping new and new weapons.

And each time more and more really good weapons will be destroyed until the developer realizes that the game is in crisis. And then they add to the game more new warframes and weapons that will be imbalanced. Players will again arrange a zerg rush on the server, and everything will go in a new circle.

Not without reason, in a warframe, unlike all MMOs, all weapons are already available at half the maximum level, after several weeks of play. And to raise the level - you need to buy and pump weapons.

Because in a normal MMO, a player who reaches the end game no longer changes weapons. He does not need it, he got the best and always uses it. But this does not bring money, so the developers went along the path of creating a kind of financial pyramid of virtual values.

Something valuable is created, the victim wants it for himself, receives it, then it depreciates and all the money invested by the victim remains in the owner of the pyramid. And he offers a new value, and so on over and over again.

This is how a warframe works. Donation Collection Machine.

[Sands of Inaros 2nd Vessel bug]

I have a similar problem.
We must kill the juggernauts in the third test. But murders just don't count. Killed at least a dozen of all the mobs that are in the third test, but the trigger does not work. The vessel does not fill up. I think it's a bug.
Sorry for the automatic translation.
