Serious Poppy Bug(Causes stuck in terrain glitch)

I was playing as Brand, and enemy team had a Poppy. Whenever she stunned me against terrain, I would be unable to move away from the terrain afterwards. If she would have left, I may have been stuck permanently. This also occurred to the Miss Fortune on our team. Step 1: Have Poppy stun you against Natural Terrain Step 2: Remain stuck there I am sorry if this was random, but it happened twice to me in the exact same match. I also didn't have video of it, because I don't normally record my matches. If anyone can confirm or deny this, please do. Thanks for reading
