unreachable in project_point_with_feature

I am not super familiar with the internals of `ncollide` so I'm not sure how to follow this bug any further (some of the internals are super complicated).

I'm attempting to have a `Ball` follow a `Cuboid` so each frame I update it's position and it works great except that there is a certain location (the same one each time) that when I go through there it panics from an `unreachable` on line 100 of `point_aabb.rs` Nothing seems really strange about the coordinates (520, 100).

Any hints about where I should look would be super helpful. Thanks!
