I'm sorry but to go threw 4 Pop'n'pills, several med cabinets, lots of loot-able trash, cabinets, ect. 7 or 8 missions, 2 traders more then 1km away from each other and 7 different vending machines, 2 air drops and not a single antibiotic at all? Something seems wrong, like it shouldn't be that level bad of luck RNG wise, kind of wrong.
With all that and more, something should have gave. That level of bad luck is unnatural.
