Hi, it appears as though classified loot, in this example medical items, are spawning in buildings around the actually intended building which in this case was the single-story blue hospital in Berezino.
Medical loot spawned in the garages, the blue car, and even the big green two-story house, that is quite a bit away. It wasn't dropped loot either, I've played the game long enough to know the difference.
Earlier I observed the same with a singlestory wooden house near the yellow two-story policestation in berezino, spawning handcuffs and a police uniform jacket.
Here go the screenshots:
