Every time in every town in every school, loot that is clearly reachable cannot be interacted with.
I have not one doubt in my mind that it is a bug.
Clearly this is nothing game breaking, but I figured it cannot hurt to make you aware. This may be something that only I experience but my friends cannot access the same loot.
I attached some images clear as day as how I cannot access the loot. Other than this location and occasionally loot that is crammed into corners I have absolutely no problems.
Nothing too great spawns on that side of the building anyway, just a buggy annoyance.
