About this Mod

Вот перевод на английский:

BigStacks is a mod for NeoForge 1.21.1 that increases the stack size of items in the inventory.

It removes the default limit of 64 items per stack and allows you to configure the maximum stack size through a config file or with the /bigstacks command.

After entering the command, a settings menu opens where you can:

Enable or disable increased stack sizes
Choose the maximum stack size (for example, 128, 256, or higher)
Configure custom rules for specific items

Important:
This mod does not work on servers!

Frequently Asked Questions

Bigstacks server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Bigstacks compatible with neoforge?

Bigstacks officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Bigstacks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Bigstacks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
