Browser: Google Chrome
Version: 1.1.4
Script: bot.user.js
This is a game-breaking bug, as nothing will show on screen when you exit from the main menu... @ErmiyaEskandary Have this fixed ASAP...

Should already be fixed with https://github.com/ErmiyaEskandary/Slither.io-bot/commit/39be4bb8771c741650356964564bda477e8ab20d , as confirmed by a few other users.
Just to be sure: you tried to remove the script, restart the browser and install the bot.meta.user.js again?
O_o where is it confirmed? it just reorders requires in bot.meta.user.js and bumps version number
In the Gitter chat room, the reordering assures the other modules are loaded before they are called.
Should be fixed now - 100%
REMOVE ALL SCRIPTS AND INSTALL BOT.USER.JS
