there was a discussion over on the steam forums about the puzzling nature of persistence on official servers. here was the confusion i posted because i too am not entirely sure if this is functioning correctly.
*copy/paste*
from what i have done...i have stockpiled 2 backpacks full of extra
food, meds, and ammo and 3 weapons out in the woods and they
have been there since thursday morning. they have not despawned yet.
i have been looking for a tent since wednesdays update to stable
with no luck at all.
as far as persistence goes i am starting to see some patterns that
i will have to make adjustments to if persistence is working as intended.
meaning, loot doesnt seem to be refreshing after server restarts. for
example, i have searched 3 different bases since wednesday and the
loot at these bases has not refreshed after server restarts. it is the
same items...in the same location...every day. i am going to be moving
my area of search to a different region of the map now to see if other
bases and cities are performing like this as well. currently, it seems
that server restarts are not refreshing untouched/undropped loot and these
items are just sitting there...for days.
