Where are the Revenant's Vault bosses

[Golyana]

I entered RV today and found only Bonecrusher, no other bosses. Yesterday they was there, I remember. Where are they gone?

Actually, I need Ice Shards for soul upgrade. Can still get it out of Vega if I'm 51lvl?

u must kill Bonecrusher before they will spawn The second boss and second to be killed to spawn Vega.

you will still get ice shard in Rev vault of any level good luck!

Thank you. I really didn't know I must kill them all in right order.
