Empty Map after Die, But Portals still available [Still in the Game]

I just died 1 time in the maps boss fight, before i cleared the map after respawn, the explored map was away, and everything in the map was gone but the boss i could kill but have to leave after Sad when using EXPENSIVE TABLETS and loose a charge for nothing

There were Similar bug reports in April this year said the search, but not recently

But its still in the game how i now experienced NOT the first time it happens more often
