This guide delivers further information on the error, pinpoint causes, and proven fixes using the latest Minecraft 1.21.1 data. Stick around—we'll have you back to building in minutes. 👍

What Exactly is the Minecraft Error: Mystery Messages?

The Minecraft Error: Mystery Messages manifests as unexplained chat spam, often showing phrases like "Information Further No" or garbled debug text. It's not a crash but a persistent annoyance disrupting gameplay. Common in Java Edition (1.20+), it hits Fabric/Forge modpacks hardest, but Bedrock players on realms report it too.

⚠️ Key Symptoms:

• Chat overflows with "Mystery Messages" like "Further information: No error detected" or random symbols.
• Lag spikes during messages.
• Server disconnects in extreme cases.
• Affects single-player worlds if mods are involved.

This error stems from debug logging gone wild, mod conflicts, or network glitches. Recent reports spiked post-1.21 Tricky Trials update due to new chat rendering changes.
