Uber Cortex crash 1662900979

Exception alert window: Attempted to get invalid index for 'm_StageDistances'.

Notes:
Died in the far right corner to a vortex/ground dot. Exception on re-entering boss arena, but not the Cortex map. 3rd set of boss pairs in the fight :( Spent all day getting uber fragments in my turbo difficult league.

Eventually cleared itself after I spent 3 portals and ground dots disappeared.
