Possible Ward Vision Bug [Gameplay]

On red side, in the brush by the raptors, there appears to be a spot where if you ward it will only show one side of the brush. I don't know if this is an intentional design or just a wonky landscape thing but I thought I should report it.

Here is the link to the picture showing what happened: https://drive.google.com/file/d/0B0famWUr5ybSRmNPT3Q0eTVRb2M/view?usp=sharing

It should be noted that the bug doesn't seem to be reproducible on blue side raptor brush: https://drive.google.com/file/d/0B0famWUr5ybSTTBGWU16VF9zdUk/view?usp=sharing https://drive.google.com/file/d/0B0famWUr5ybSTV9LeEQyd1dZNDQ/view?usp=sharing

I didn't include steps to reproduce because it's as simple as placing a ward in the brush along the wall that I have placed mine, however I'd elaborate if needed. Hope this is helpful
