Stack Fix
by Instaboomer
Stack Fix changes how far Forge items stack, so inventories hold more of the same item before a slot fills.
What it does
Stack Fix sets items that normally stack to 16 so they stack to 64 instead, which keeps inventories from filling up with partial stacks. The author notes it covers the items that tend to clog a pack, including Ender Pearls, Eye of Ender, Armor Stands and Written Books, though the exact list is set by the mod.
The mod is server-side only, so only the server needs it and players join without installing anything. It is published for Forge alone, for the 1.7.10 and 1.12.2 game versions, with a single release, 1.0 for 1.12.2, dated 2024-02-18. The code is released under All rights reserved and is not open source.
Key features
Larger item stacks
Items that normally stack to 16 can hold up to 64 in one slot, reducing the number of slots a backpack needs.
Covers common clutter
Ender Pearls, Eye of Ender, Armor Stands and Written Books are among the items the author lists as affected.
Fewer clogged inventories
Partial stacks are consolidated, so inventory space goes to unique items rather than half-full stacks of the same thing.
