Heart of Deimos - After activated the two crystal to open the vault nothing happens

[FireDevid]

As you can read from the title doing the isolation vault mission nothing happens after i activate the crystals.

(my type of vault is the variant E of the wiki: https://warframe.fandom.com/wiki/Isolation_Vault)

So i wonder ... is it a bug?  or am I not understanding the next step?

P.S. sorry for my bad english

you don't activate any crystals to open the vault. you shoot the one in front of the vault door, then loid/otak floats around and does stuff before returning to the vault door, then you shoot the 4 crystals in the vault door room to open the vault.

the various other crystals around the map are for opening bonus rooms with crates and stuff.

You have to activate 4 crystals in the correct order.

Thats for the vault, the 2 crystals he is talking about open a secret door with a 3rd crystal behind it that reveals breakable statues.
