What's new

First public release. Phase 1 of the design is complete: stacking works, is safe, and gives every mob back if you remove the mod.

Requires Fabric API (not bundled). Minecraft 26.2, Fabric Loader 0.19.3+, Java 25+.

What works

Merging Same-kind mobs merge once a crowd of 4 forms, counted by true mob count
Count label Shown on hover via the mob's custom name, so vanilla clients need nothing
Breeding safe Babies, animals in love, and animals on a breeding cooldown never stack
Vanilla breeding Feeding a stack releases one member as a partner and puts that animal in love, never the stack
Auto rejoin Bred parents rejoin the herd once their cooldown expires
Death handling Killing a stacked host promotes a member instead of losing the stack
Persistence Stacks survive world reloads and server restarts
Commands /mobtimizer unstack all, here [radius], type <id>, plus stats and reload

Not in this release: damage routing by source, scaled breeding (100 wheat yielding 50 babies), scaled production, and mob-cap reporting.

Known issues: stacks created before this release may still contain babies (/mobtimizer unstack all clears them); a stack loses one member per breeding pair while they court; /mobtimizer stats reports "1 stacks"; and this has not been verified alongside mods that rewrite entity ticking or death paths, such as Lithium.

Marked Beta because it is a first public release play-tested on cows and sheep only. Bug reports very welcome: https://github.com/Aff55/Mobtimizer/issues
