SP Omnia Fissure - Void Cascade

Hello guys.
What are the chances to play Omnia Fissure Void Cascade these days?
Me and my friends are trying to open our relics and we want to open them in SP Cascade.
But it seems impossible to catch this activity. It appears like 1-2 times in 24hrs and always when we're sleeping or working.
Every time i open the game it is Void Flood or Survival.
Rotation is broken or what?
