@Geez, the problem is on your end.
Non-persistent servers do not spawn anything at all as of this update. I fail to see how it is the hosting's fault. That was after all your decision. Somehow, somewhere, some idiot thought that "let's force persistence, but let's leave an option to have it off so there's no loot there". Didn't know you guys employed Dr. Evil.
Persistent servers spawned plenty when the update went live, partially due to the broken loot tables (apparently being able to find smersh vests in sheds was a bug), partially due to the fact it was a total reset. After that there is nothing. I went through military bases that have not been visited lately finding nothing of value (after going through about 10 of them, making sure the servers in question were persistent, the most useful item I found was an orange drybag). Heli crashes also spawn NOTHING AT ALL anymore. Aside from the most basic items, loot just doesn't seem to be respawning, maybe because things that already spawned are blocking the spawns (in case of which they should be deleted to make room for new).
Persistent servers always had trouble with item spawns. Ever since persistence became a thing, a server being persistent outright meant "you won't find anything here" until about .53, where item spawning was improved (at the cost of running into loot-stacked areas).
Non-persistent servers were a counter-weight against that. You wanted loot you went to a non-persistent server. You were guaranteed that there will be stuff there. You were not guaranteed any specific item, but basic necessities were all there. Now that counterweight is gone.
There is no interesting loot anywhere at this point. Around the time where the update went live I would find numerous guns. Right now, there is god damn nothing.
Saying that it's the fault of the server hosting and not yours is just simply dishonest and immature. It's shoving responsibility for this screw-up of an update to people who had nothing at all to do with it.
If you people cannot create a loot spawning system, that's not a complete failure, then at least leave non-persistent servers as loot zones. Some people are masochists that enjoy looking 12 hours of cans of beans, most aren't.
#Edit:
I've been poking around and from what I can tell, stuff simply isn't re-spawning, at all. It spawned ONCE, probably during Wednesday maintenance, or when the update went live (whichever was sooner), and nothing since then.
This is particularly evident with heli crashes. If another heli crash so happens to be on the same field, what you'll most likely see is the following: an empty helicopter and some leftover loot from the original spawn lying around on the grass somewhere (most noticeable in areas where helis have a dispersion radius).
This also explains why there isn't crap anywhere aside the deepest reaches of the map.
I went to some villages outlying Severograd and I actually found some food up there, my guess being that I was the first one to bother to venture there on the particular server.
