Is it only on one server? Do you notice it in singleplayer?

Also what MC version is it?

This should not be related to Aristois. Are you a donor? Do you have any addons?

Caused by: java.lang.RuntimeException: An error occurred when trying to find the optifine jar: INCOMPATIBLE

Either there is no optifine jar file in your mods folder, the one there is outdated, or you have multiple. You need to either uninstall optifine or manually add the correct optifine jar back.

To uninstall: https://discuss.aristois.net/topic/13/how-to-uninstall-optifine-optifine-error-on-startup

Are you using an unofficial launcher?

Try deleting .minecraft/libraries/me and restart the game and launcher.

@to If you mean that it tells you to update in-game, please follow this: https://discuss.aristois.net/topic/23/invalid_checksum-error

Hello, I'm not sure what you mean by this. Can you please explain what the "BotFilter" is or what it says when you attempt to pass it?

For future reference, it says what you need to do

@TacticalModz @Valenkus It's been fixed now. Restart your game and launcher

Adjust your minecraft brightness in-game and restart
