For “1.20” forks:
| Problem | Solution |
| :--- | :--- |
| "Could not load WASM module" | Clear browser cache. Disable ad-blocker (it blocks WebAssembly). |
| Audio stuttering | In Chrome, go to chrome://flags → Enable WebAudio to use WASM. |
| World won't save | Increase browser storage quota. Go to Site Settings → Storage → Allow up to 2GB. |
| Connection refused | The server is offline or requires a whitelist. Use the Eaglercraft Discord to find active 1.20 test servers. |
| Crashes on Armour Stand | Known 1.20 entity bug. Run kill @e[type=armor_stand] via command block if you’re OP. | If you truly love Minecraft, buy the official game
