If you have launched EV3-G recently, you probably discovered that there is a new update! LEGO has released version 1.2.2 to address the “VM Program Instruction Break” bug. Be sure to update your software to the latest version. The bug did not affect the firmware on your EV3, just the compiler in EV3-G.
The Seshan Brothers, over at EV3Lessons.com, have an excellent overview of the bug.
