I was opening my MC launcher on 1.10.1 and went on a server, CubeCraft specifically. I expected to play some EggWars and play like normal.

Instead, the game crashed and showed this message:
---- Minecraft Crash Report ----
// Why is it breaking

I cut out the rest because there my computer system info was in the message.

Steps to Trigger
1. Open Minecraft.
2. Click on "Multiplayer"
3. Go on any server.
4. It should crash. Simple as that.
