Anivia get's stuck at the Mid gate of the Southern Base, on the right corner.

Was playing in the enemy base near the mid inhibitor on the south side of the map.

When to go ward the enemy's wall and then started to walk away from the base as theywere coming. I couldnt move . I could not go forward. I was stuck in the gate's corner, out of nowhere. The only way out was moving backwards and then i could move but then it was too late. This cost me a life . please fix
