[GAMEPLAY] Vision Issue

It's your typical run of the mill vision bug that seems to popped up in games recently, namely ones at Worlds, but also ones occurring now. There is a similarity in the example provided in the image album, though. The issue is with the pink ward's ability to see other wards.

This type of bug is difficult to understand because physically, there should be no obstacles blocking vision of the enemy green ward, but somehow it manages to happen.

There are no 'real' steps to reproduce this bug other than to exactly place a pink ward where the one in the pictures was placed and to place an enemy green ward on the other side of the bush as shown in the first picture. In case someone would want to know exactly where the wards were placed, my replays are public. Sorry I can't be more helpful, but that is the limitation put on us :(
