My fireteam had gotten to the final round of PoE 32 when my friend was kicked from the game. He tried rejoining and it said the fireteam was full. I sent him an invite from inside the game (I was fireteam leader) and he still couldn't join. So I opened the party app and invited him to it. Once he was in the party I invited 'party to game' and instead of him joining us at the end boss it took myself and the other fireteam member up to orbit where my friend was and we joined him, setting him as fireteam leader. Granted, level 32 isn't that difficult, but I was helping two lower level guys get their armor core and it was frustrating to lose that time and effort. Don't know if this is a Destiny server error or xbox live error, but something similar happened last week and I think it would really help if they put checkpoints in the PoE.
