how did you make that to happen>? From all the post during the weekend the item should be different but the mods should be the same. Did they do another silent update this morning to fix it.
Because not all item types in the game are procedurally generated. I suspect some items are hand placed or the container has a loot table that consists of only 1 item type. Even if every part of the item - its type, its attributes, the number of attachment slots and the mods were procedurally generated, it will always roll the same type, although not necessarily the same attributes, number of attachment slots or the same type of mods. 8ug8ear's safe always had a Military-grade Aramid Netrunning Suit in it and nothing else. This was true before patch 1.1.
All themed legendary clothing items are either hand placed or the containers that house them have only 1 item type that can spawn in them - the themed legendary, some data shard and whatever else usually accompanies them. We know prior to patch 1.1 that the number of attachment slots and the mods on themed legendaries were procedurally generated because we save scummed to get max sockets and maybe crit mods like Bully and Fortuna.
From what I can tell, there are broadly two types of loot container - static containers and corpses. I think we can be reasonably confident that most corpse loot is procedurally generated using a random seed method derived from the xyz coordinates of the npc at the moment it's health is reduced to zero. When that happens, a death animation triggers and an invisible container spawns at the coordinates where the npc died (the corpse container). Inside the container will be some item whose type and stats are pseudo randomly generated from (I'm assuming) a pre-determined loot table. Because it would be crazy if every npc in the game could drop every item type, at any quality (even with minimum level requirements).
NPCs often carry weapons and the weapon type is not procedurally generated (although the attributes, attachment slots and mods can be). For example, in West Wind Apartments (in Pacifica) there are lots of Scav groups that I farmed for exp in a loop. Most of them are equipped with knives and when you kill them, they will drop knives from common to rare quality. They will not drop any other type of weapon, no matter how often you respawn and kill them. Even at level 50, you will never see one of them drop an epic or legendary knife. The scavs with guns will likewise only drop the gun type they are using (again, always common to rare quality, never epic or legendary).
NPCs may also have hand placed items on their corpse or special rules determining what quality they are - Oda for example will always drop the iconic Katana "Jinchu Maru" and 2 legendary quality items - 1 weapon and 1 item of clothing. I think the item of clothing will always be an Arasaka Vest but the weapon can change depending on where you kill him. This could be wrong though because I haven't tested it and gotten reproducible results. Matilda K. Rose will always drop 2 legendary quality items - 1 weapon and 1 item of clothing. Both items can change depending on the coordinates she is standing at when she dies. It does not matter what your player level is. These items will always be legendary quality. As far as I can tell from killing her like 50 times in different locations, she can drop 1 of maybe a half dozen specific types of clothing? She can't drop every item of clothing in the game.
Static containers can be like 8ug8ear's safe and always drop the same item type, or the contents can be procedurally generated. I cannot confirm if the attachment slots randomised in 1.06 but I don't think they ever had mods in them. Where static container loot is randomized, I'm guessing it is done via a different seed method to corpse loot because unlike npcs, static containers do not move. Or maybe this is bugged and that is why loot that we suspect used to be procedurally generated is now the same for everyone. We don't have a good theory about why this is right now.
To test any theory we would need some people to roll back to 1.06 and identify a static container with procedurally generated loot. The only one I have been able to identify as a good potential is container A in Megabuilding H6 because I save scummed the shit out of it in 1.06. I then used Cyber Engine Tweaks to set character level to 50 and got Legendary Boostknit Neotac Pants from it. I then reloaded before I set my level to 50 ( I was level 31 at the time) and left the building without looting the container. The idea being that I would come back when I was level 40 and pick it up when it could roll legendary. Patch 1.1 deployed before that could happen and now Container A always has 'Trendy Sazan Lily Square Glasses" instead. On multiple characters and across multiple players. We don't know why this is happening.
