CobbleOptimizer 4.3.2 — Patch Notes

Fixed: ghost Pokémon after batch despawn

Sometimes when the mod cleaned up extra wild Pokémon to keep TPS healthy, you'd still see them standing around on your screen — they couldn't be interacted with, didn't move, and only disappeared after relogging or moving far away.

This happened because the server removed the Pokémon, but in some cases forgot to tell your client about it. Now the server sends an explicit "remove this entity" message to every player who could see the Pokémon, right at the moment it gets despawned. No more invisible-to-the-server ghosts cluttering your view.
