Bigger stacks

Allows you to increase stack size beyond

64, up to ~1 billion (though I don’t recommend you go that high).

The mod allows you to change the stack

size of items based on tags, what mod it comes from, and more using
rules.

When you load into a world with the mod

unconfigured, it will show you this prompt:

width=”594″ height=”168″ />

Clicking on the command or running it

will open a configuration GUI.

You can open this GUI at any time by running /biggerstacks quicksetup

With a mod like this, it is very likely

that some things will be incompatible. If you find any issues, or things
not working as expected, report them on codeberg.

Some item transport mod (xnet, modular

routers, pretty pipes, cyclic) have been changed for bigger stacks.
There is some more information about the changes in the config
file.

**Please

report any issues/incompatibilities you find with this mod to me, not
the author of the other mod.**
