I disagree - first off Cozmo didn't "call out" anyone and certainly didn't state the OP was "a liar". He was just correcting misinformation. Could it turn out Cozmo is wrong because the software has a bug and isn't performing as intended? Sure, it's possible, but he's stated the behavior of the game and Bungie's policy as defined to him. Again, since Bungie hasn't said what's causing it, we don't know if the OP is right or not.
