i have been making manual saves often (bad experience before not with this game but just incase) but the thing with the mission is also confusing to me as when i trigger the delivery nothing changes except for consuming the 30 chocolate bar (and something else tho i haven't read what and it doesn't appear in the requirements ) and debilitating 1 random character of the team. I have tried doing 2 delivery as to keep track of time and even tho the normal delivery completes the mission one doesn't and i can't even recall it as it doesn't even activate it stays the same
