I'm sure this is a known issue but couldn't find a report about it for exp.56 so (for my own peace of mind) here we go :P
There are still certain places with massive piles of loot spawning on top of each other. For example the prison (island) is like a clothing store, with hundreds (possibly thousands) of ttsko/gorka/orel etc. pants and jackets. Some of the un-enterable porch buildings have massive piles of vests/AKs/SVDs/pistols/mags etc. Military watchtowers are another example. This is obviously taking these items from the loot system and concentrating loot at certain points on the map.
