Without any mods... If a player edits of any soldier, by means the Eden editor in the Virtual Arsenal(to be precise, use the context menu), then always after this, in the game, the player can not open his backpack and use the contents of his backpack.
Note! I do not mean "open suborditane inventory" command, I mean, when a player comes to ally and opens his backpack. After trying to do it, in the inventory menu of player, always this backpack would be a empty, but actually this backpack has ammo or other things. Thus, any editing by means EDEN and Virtual Arsenal, kills the opportunity use allied backpacks. Please fix this bug.
