The shed in the Pavlovo Church graveyard has a second shed inside it. This duplication is the most obvious of the three because the inner shed is smaller so you get to open two doors to enter.
The green house to the South of the church and also its shed are also duplicated but with these you have to enter the buildings and close the door from the inside in order to find that it has two doors in the same place. There appears to be two identically sized buildings, one inside the other. This green house is reported to have minor loot explosions on busier servers see 0027225.
So duplicated sheds might also be the reason for the high loot reported in 0027078.
