This pertains to version 20w14~, which is not an option on the Affects Version/s drop-down menu. I'm aware that the April Fools issues will be closed, but this is important. Please read this all the way through. Also, I'm on Mac.

In the April Fools snapshot for 2020, 20w14infinite (20w14~), there are certain warps that cause the game to crash. Most of them are just a standard crash, where the game closes, and then you can reopen the game and /warp somewhere else before the world loads in. However, there is one warp (possibly more) that causes the game to be completely unopenable. And by unopenable, I mean that even the launcher refused to open. I was unable to move the launcher to the trash, as Mac OS X prohibits moving applications that are open. I was forced to re-download Minecraft entirely.

EDIT: When this happened, it also crashed another Java application that had been running in the background.

Steps to reproduce:

1. Open 20w14~.

2. Create a world.

3. Type "/warp missingo" without the quotes. All lowercase and it is "missingo", not "missingno".

4. The game will freeze for approximately ten seconds, and then crash. Attempting to click on the Minecraft game logo on the Dock will do nothing. To fix this, you must re-download Minecraft entirely.
