Item Split Bug Fix
by iwaliner
Item Split Bug Fix addresses a Forge problem where stackable items split apart and stop merging with identical items in some modded setups.
What it does
In some heavily modded environments, items that should stack refuse to merge even when they are the same item. The cause is a pair of blank NBT tags, and this mod targets that cause. Installation covers the server and each player's game. Files are published for Forge on 1.20.1 only, and the latest is 1.20.1-1.4 for 1.20.1, released 2026-07-11.

In some modded environments, items cannot stack even if they are the same item. This is because one of the pair has a blank NBT tag.
