[VISON-SHADOW] Bug when you RECONNECT in Game

So i have noticed this issue numorous times now, everytime i dc from the game then i reconnect , something weird happen to the map, so basically some zones where they should be no vision and should be SHADOW, they become clear as if it's warded all the game (NO SHADOW). and it's so frustrating because sometimes you can see with that bug that you have vision, but it's just the shadow bug, and an enemy might be there waiting for you. by the way i took screen shot if you guys interessted to see my problem , i don't know if you guys understood what i meant, because it's hard to explain it.
