I have been checking out the first build of 0.56, and I have not noticed the following items despite ardent and thorough looting of the whole map (starting from Berezino - Krasnostav - Novy Sobor - Stary Sobor - Veresnik Base - NWAF - Vybor - Pustoshka - Zelenogorsk - Green Mountain - Rogovo - Nadezhdino).
Items in question that do not spawn are:
-Cooking Pots (probably pans too)
-Sewing Kits
-Leather Sewing Kits
-SVD magazines
-Hunting Scopes
