So when I save and quit on ODST, I should immediately be able to pick up on the last checkpoint. If I l go to the Playlist, hit resume, accept scoring and then launch I am able to do the Iron work around. But unlike the other Halos, when I go to just hitting start in the playlist options (not selecting the Playlist im doing) the mission resets. So for anyone who does Save and Quit for the LASO make sure you select the playlists and resume. ODST is my last LASO but easy. So I dont care if the mission resets. For the people who do care be carful, just putting this out. I dont know if its just me but PSA.
I would always recommend to test any tricks before performing them in a sharp situation. This should be done in order to avoid the most basic mistakes.
