eris: ERR_UNHANDLED_ERROR after updating to 0.11.2

I seem to have run into an unusual issue after updating from 1.10.1 to 1.11.2. Seemingly out of nowhere, the bot sometimes throws this connection error, causing my game server to crash and restart.

[5022.558]: [INFO] An unnamed player rejoined the game! IP: ::ffff:37.192.190.132. Player ID: 464148. Players: 1.
[5068.763]: [INFO] An unnamed player has disconnected! IP: ::ffff:37.192.190.132. Players: 0.

Currently, I use WebSocket version 7.2.3, though it seemed to work fine with 1.10.1. I’ve also noticed how the bot seemingly looses connection at random without crashing the server, instead running bot.on("ready".... I’m not sure if that is normal behavior, but here’s an image to represent a few times the bot has done this: So yeah, that’s quite a mouthful. Haven’t found any issues similar to this, so here I am. Maybe this is just an easy fix that’s been hiding under my nose, but I haven’t been able to find it.
