Maybe, maybe not, but I sure haven't heard of this, let alone seen it before. I just flew right through a spheroid! I just sort of accidentally moved a certain way, after a button-hook, and the spheroid sorta did the same, and I flew right through it - or we passed through each other, perhaps - very similar to going through a ghost in Pac-man or Mspac. Fortunately, I was smooth enough to go with it and carry on, but still it was quite astounding.
