Posted December 10, 2025Dec 10 Me and a couple friends are playing Cobblemon BetterMC with a couple added mods on NeoForge. Every single time someone inserts or ejects a music disc from either a jukebox or a backpack my game crashes with this error: Internal Exception: io.netty.handler.codec.DecoderException: Failed to decode packet ‘clientbound/minecraft:custom_payload’ I’ve search several sources based on this error but none have resolved the issue.I’m playing on Steam Deck through PrismLauncher and the server is played through Essential. Any help is appreciated and thank you for reading.
