LiquidBounce 1.8.9 b62 had an issue which caused lag when placing/breaking blocks. We have only just noticed and uploaded a fixed version. We have not incremented the version number as this is not a real update. This means the affected LiquidBounce version has to be replaced manually with the new one. This can be done by simple re-downloading LiquidBounce 1.8.9 b62 and overwriting the existing file.
How to update with LiquidLauncher1. Open up LiquidLauncher.2. Hit Settings and click the folder icon next to the installation path. An explorer window should pop up.3. Navigate to versions/1.8.9 and delete the folder called b62.4. Close the explorer window.5. Now simply select LiquidBounce 1.8.9 b62 in the settings tab, press Play LiquidBounce and you should be prompted to download LiquidBounce again.
Sorry for the inconvenience.
