1.1.0: (1.2.1) Integrated Server Error

[Plet53]

Version:
1.2.1

What is the bug:
Upon attempting to launch a world, either freshly created or previously made, my game crashes.

Can it be repeated:
I'm not certain. This occurs every time I attempt to launch a single player world.

Known Fix: Deleting usercache.json, located within the minecraft folder of the specific installation

Apparently.... Google is the issue??
Weird. Have you tried the usual "backup your stuff/reinstall everything" yet?

Its not Google that is the problem. The json function causing the error is from Google's libraries. Looks like the player cache is corrupt. Which uses json to store its data I'm guessing. However, you are correct that a reinstall will fix it.
