I was soloing the new quest for Vexcaliber (which took over an hour for me so far) and I finally made it to the final phase of the final boss fight. I knocked off about 1/4 of his final bar (his head had fallen off at this point) and I got returned to orbit. No disconnection at all, instantly kicked to orbit with this message: "You have been returned to orbit. Please try again. If this problem persists, you should troubleshoot your networking setup. For more information, visit help.bungie.net and search for error code: calibrese." Please Bungie get me a checkpoint to that final phase somehow...or at the very least back to the final boss.
