// I have not thoroughly tested this to see if it works. Preliminary testing suggests it does.

// What this does:
// - Clears the chat inputs after a delay after the round ends so some characters don't stay
//   bonk.io does it, but sometimes leaves a few characters if you're typing whilst the round ends

// I need to use semicolons correc;tky;;;;;
