Frequently Asked Questions

❓ General Questions

Q: Will StackableTools work on multiplayer servers?
A: Yes! The mod works on both single-player and multiplayer. Server-side mixins handle all stacking logic, so clients don't need special configurations.

Q: Does StackableTools break vanilla survival progression?
A: No. Tools still require appropriate materials, and durability still matters. Stacking just saves inventory space.

Q: Can I disable the mod without deleting the .jar?
A: Not directly. However, you can set enable = false in stackabletools.toml to disable all stacking features.

Q: Does this mod work with other mods?
A: Yes, in most cases. StackableTools uses Mixin — a standard modding framework. Compatibility depends on whether other mods also modify the same Minecraft classes. If conflicts occur, load StackableTools later in the mod order.

⚙️ Configuration Questions

Q: How do I completely disable potions stacking?
A: Remove "POTIONS" from the active_categories list in stackabletools.toml.

Q: Can I make armor pieces stackable?
A: Yes. Set max_armor_piece_stack_size = 8 (or your desired number) and add "ARMORS" to active_categories.

Q: What happens if I set a stack size to 0?
A: Items won't stack (treated as 1). The minimum practical value is 1.

🐛 Bug & Issues

Q: Items won't stack even though I've configured them to.
A: Check your stackabletools.toml — make sure:

  • enable = true under [stacking]
  • The item category is in active_categories
  • The item isn't in excluded_item_ids

Q: The mod crashes on startup with Mixin errors.
A: Ensure you have Fabric Loader ≥0.18.5 and Fabric API installed for your Minecraft version.

Q: Stacking works in creative but not survival.
A: This is expected if you're using a server without the mod. Install StackableTools on the server.
