I am in the Berezino area and I've noticed lack of items in upper and lower Berezino. I originally spawned in Svet and was able to find a ton of items at gate houses (the one with the stoop), and various other houses.
When I moved south, Berezino seems to be bare. I have noticed this on Southeast 0-1, Central, and the Southwest experimental servers. I have been playing Experimental since Thursday when the roll out occured.
