Collision Problems

Ok, so I have made this grid and have selected some vertices and raised them up to form somewhat of a pit/ramp. I made an UVsphere, and am trying to see if I am able to drop the UVsphere in or at least watch it roll inside of it. I have done everything I know (which ironically isn’t much at all), and it still has these small parts where it dissapears below the grid and then bobs back up and then stops. What in the world am i doing wrong?


bounds type a sphere?
