Viridian Wildwood bug

Today when I was running in endgame a bug appeared. It happened when I finished Viridian Wildwood and died at the same time, the atlas book dropped. When I come back I accidentally walk in the dark place which teleport me to the other part. Then I lost my atlas book.
P/s: I tried to rejoin and also tried to go to other viridian wildwood and it still didn't drop
