Changelog
In version 4.0.1 we fixed a bug where players with Pokémon that have pending evolutions (like Eevee) could get disconnected when joining the server. The issue was caused by a Cobblemon bug where the game tries to load evolution data before the Pokémon species registry is ready. Instead of crashing, CobbleOptimizer now safely skips the evolution display and lets you connect normally.
