as you can see the particles are completely ignoring the wall to the left and they all go straight through
the floor also is a collision object but it has no problems as the particles hit the floor and slide across. i checked the normal directions of the wall, tried baking the rigid body cache, gave them the same settings, changed the shape of the rigid body but to no avail. keep in mind the particles has the size deflect checked as it still works for the floor. i dont understand what is causing this.
