When having an enemy Dark Willow, the black ground texture effect of Bramble Maze sometimes appear at places where DW had cast it before outside of vision.


Repro:
1. Have an enemy DW cast Bramble Maze anywhere outside of vision
2. After the maze expires, gain vision over the area

Result: The black ground textures of the spell may appear there and stay for a couple of seconds, even though the spell already expired completely.
