SMX 120 Slot Backpack Perk Adapter is mainly worth checking through 120-slot toolbelt, slot count, carry capacity, and encumbrance, containers, quick stack, and item transfer, crafting queue and recipe material use, shared storage on multiplayer worlds, and inventory, backpack, and toolbelt screens. Do that in a copied save or test server before changing a main world.
Use Nexus Mods listing to confirm exact file names, branches, screenshots, and update notes; then judge the MOD by the in-game parts above, not only by whether the game launches.
- Check hotkeys, item movement, vehicle access, and restart behavior with the exact slot count.
- Fill slots with real loot, die once if relevant, restart, and check whether items remain valid.
- Move mixed stacks between player, vehicle, workstation, and base containers.
- Queue several recipes, leave the menu, restart, and check materials and outputs.
