I saw some of those in the bank as well, though none in the vault. As far as I know they only ever hold books or paper.
I'm not sure I've seen a morgue with these boxes used as cold storage. Or any morgue at all; I've seen plenty of churches and funeral homes, plus the western version, and the woodworking shops with caskets, but I don't recall seeing any morgues yet. More to explore!
Gotcha. The box was just big enough I wondered if it could hold something inside, and I just needed to be patient enough to crush them all. Kinda a letdown; it would be nice to see safety deposit boxes. Something special for banks, different loot list with cash, diamonds, and pistols 😆
Thanks! I'll keep an eye out for the lootable version.
