Yeah.. it is odd. The staples do have continuous interpolation set on them, and I had made the moth colliders thicker. I was also chasing a bug where if you replay in the same session it left the pool items in an inconsistent state, creating "zombie moths", impervious to stationery! Could be the return of that bug... and, that could even be the sequel! On the win version it's easier to see if you're over or undershooting, could be that.
