Depends a lot on what glitch, you should be more accurate on your questions.
You can however place Charon next to player if he's stuck or if you don't know where he is, etc..
First I must explain that the game follows this way of identifying itself:
Open up the console and type: player.placeatme 156f6 1 1 1
There's a space in between the "1" numbers after the "156f6" character ID, because they are coordinates, so don't forget to space them..
