Contact between a ball and cuboid sometimes and has no contact pair

[Dooskington]

Managed to capture a gif of it happening, and the log at the same time. 55 is the ball, 45 is the brick that it gets stuck on.

step
contact started: handle1: Index { index: 55, generation: 4 }, handle2: Index { index: 45, generation: 0 }
No contact pair found for collision!
step

It seems like it happens more often at the borders of the bricks, i.e. where two Cuboids are basically stacked right next to each other.

I just had this happen again, but CCD was disabled:

step
contact started: handle1: Index { index: 54, generation: 0 }, handle2: Index { index: 44, generation: 0 }
No contact pair found for collision!
step
step
contact started: handle1: Index { index: 54, generation: 0 }, handle2: Index { index: 43, generation: 0 }
No contact pair found for collision!
step
step
step
contact stopped: handle1: Index { index: 54, generation: 0 }, handle2: Index { index: 44, generation: 0 }

I think this may not be specific to CCD, but having it enabled seems to make it worse.
