[GAMEPLAY] Pink ward give vision over walls on insivible enemy

Found out a bug, it has been here for many patches but I think it should be repported because no one does.

It's about the pink ward, just put the pink over a wall and a green ward the other side, normally you will see only "non-invisible" enemies, but you can see them...Plus, this enemy doesn't even have the information that he is seen.

ps : You can see only if the enemy is in range of the pink ward, not green ward

Steps to do : Buy a pink and green ward, put the pink on a side of the wall, put the green to the other It's happens always, 100% reproduction rate
