Hi
Since the May update all the colored loot boxes (red, yellow, blue, green) have been empty. The dark green ammo boxes (ones with the yellow symbol on the front) are fine and so are the backpacks and gun boxes, it’s just the other types that normally hold misc loot (gas bottles, flares, med kits etc). This has occurred over several sessions and when I hosted a co-op game (1 other player).
I’m lvl 14 running the game on a PC.
Hey spanners, and welcome to the GZ community! Thanks for your bug report. This is a known issue that has been sent on to the devs 
Hoping that this will be fixed in a future update! It is currently affecting just about everyone it seems.
Yea it’s affecting everyone who’s past the starting island. Those tool boxes sometimes actually have stuff, I noticed on the new game I started the other day, but in my main game, I played for like 4 hrs today and every single coloured tool box was empty.
I have also reported this issue and am waiting on a fix. Do you know by chance if the update will be done soon or are they waiting to release during their next interval that’s like a month out?
I have the same problem. And ammo boxes contain very few ammunition.
You can increase the amount of ammo you find with the Salvage perk It’s always a must -have for my builds
