[GAMEPLAY] Parts of Amumu's Ult are not visible when used on a ramp.

When Amumu ults on one of the ramps at the edge of the river (and some other places on the map), large portions of the Ultimate's effects will be invisible, covered by the floor textures. This is a major visibility issue, since the Ultimate still affects enemies within the radius, but no particle effects are visible.

1. Start a game as Amumu.
2. Stand at one of the ramps that exits the river.
3. Use your Ultimate ability.
4. Notice large parts of the Ultimate are not visible.

This bug has a 100% repro rate, and affects many areas around the map. Examples are provided in the linked album (happens in both bot and top side river, I only provided examples in bot river).
