Might be helpful: I've never been hit by this bug, after I heard about it I figured it was something to do with colliding into the next model while it spawns and I just stay as far away as possible while gathering. Crouching or standing, no difference, just as far away as possible (crouching is actually better for this). Haven't played on a fall damage off server since the patch either.
not trying to single you out specifically, but more to illustrate the point of this thread isn't to tell people how to avoid this bug, but more on how to reproduce it reliably so the devs can fix it :)
