Instanced Containers
This mod makes loot chests and barrels be instanced to each player(Server-side)
About this Mod
This mod saves the loot in each generated chest, so that later players can still have loot even after it is explored by other players.
This mod only works with chests, and barrels, and due to some limitation of making it server side, when 1 player is interacting with a chest, no other player can open that chest.
