How does it feel like to be a GM in an MMORPG or a VRMMORPG?

The 2 close friends, Matt and Liz, are special created AI's to remove the bugs in their game. Normally you would think that you need to rewrite the code, but in this game you need to kill the bug to completely remove the bug.

2 weeks before launch, they get the permission to get a headstart to level and find hidden bugs. After 4 weeks they become famous around the world and they get the nickname [The Masked Twins], little did other players know that [The Masked Twins] were hidden GM's that were hunting for the bugs. While the two were playing they encountered a bug and their new close friends find out about their exploits.

How will Matt and Liz continue play the game and remove bugs? How will they go outside without a real body? They are robots and their creator, Juliet, always has a resolve for these things.
