So have if you want to fresh run a hard raid...but you accidentally grabbed your friends checkpoint. your screwed!!! So it is IMMPOSSIBLE To fresh start it unless you join someone else who has not started it... If it says reset it is offering to reset the Normal raid that you have a checkpoint on. If you click on the icon for the hard...you can't reset it, it just continues from that part I really wish people at bungie actually tested there stuff... For Example: Necrochasm (at anytime ever), vex (Pre-Patch), Vex (Weapon Patch), NLB (Any time ever in the history this weapon), Etc...Etc...Etc
