I have 14/20 lost letters,16/20 Mohan Ghale's journal,33/40 mani wheels,44/55 masks of yalung and 143/150 propaganda posters.I looked everywhere but I can't find anymore of those.It seems that propaganda posters and mani wheels respawn just like loot crates.I want to know if this is true and if other collectibles are the same?Because I swear I already found some propaganda posters,masks of yalung and mani wheels at the same locations multiple times.This is weird...
