Movement Stops on Pink Ward (Major)

This has happened to me twice now and was consistent. Basically placing a pink ward in a particular bush will stop me from moving through it.

Repoduction Both times I was playing Sejuani using the Poro Rider skin I would buy a pink and then place it in the bush to the right of baron (Linked image shows the bush I mean. The lower one in that image) At any point during the game walking through that bush and ward will stop my character completely and remove my current waypoints. You then have to walk back and around the ward to continue.
