Available for:FabricNeoForge

Changing a Pokémon's form in Cobblemon should be exciting — not a source of broken movesets. Cobblemon NoValidation Mod is a lightweight fix by YajatKaul that tackles the frustrating "form changes move set issue," where Pokémon lose access to valid moves after switching forms. If you run a Cobblemon server or play solo and rely on form changes, this small patch keeps your movesets intact so you can focus on battling instead of debugging.
