Flan Cobblemon Extension
by lilpebs
Flan Cobblemon Extension lets server owners stop Cobblemon Pokemon from spawning inside claimed areas and turn off the new Cobblemon Display Case interactions where claims apply.
What it does
The extension links claim protection to Cobblemon. It supports Pokemon spawn prevention inside claimed areas, plus a set of smaller additions, and a claim area can be configured from the claim menu. Claim permissions, display case settings and Pokemon spawns do not carry over from older setups, so claims may need to be re-enabled after installation. From version 1.2.0 onward, a data pack is also required alongside the mod.
Cobblemon, Fabric API and Fabric Language Kotlin are required dependencies. The mod is Fabric-only and runs on the server, so clients may leave it out. It is released under the MIT License, is not open source, and covers 1.20.1 and 1.21.1 in its release files.
Key features
Spawn prevention in claims
Cobblemon Pokemon spawns can be cancelled inside claimed areas, keeping claimed land free of wild Pokemon.
Cobblemon display case controls
Interactions with the new Cobblemon Display Case can be disabled for the server.
Claim menu entry
A Pokeball icon named in the claim menu opens the extension's claim settings on its last page.

What the author says
Claims should remain intact, however, the permission setting for display case and pokemon spawn cannot be migrated currently, thus you'll need to re-enable them in your claims. Simply claim an area, open /flan menu, head over to the last page and a Pokeball with the name POKEMONSPAWN will allow you to cancel…
