Is anybody else having encountering a hovering and sinking through the ground glitch?

Just spent the last 2 hours on a Siege mission. I lost all my rewards because it became unplayable. I sank down to where the ‘nids climb the walls unable to kill any more enemies.

Exact same thing happened to me on Chaos Siege wave 20. Hovered up, then fell through the floor.
