In The Elder Scrolls V: Skyrim for the PC, PS3, and Xbox 360, there are a lot of followers in the game that can tag along and help you fight, carry your items, etc.
The AI for these followers isn’t always the best, so they can get into trouble sometimes and lose their way. Typically they will try to find a path to you, but every now and then they can get lost, so what do you do?
The first thing to try is to Fast Travel to a new location. Bring up the map, click on a place you’ve visited before, and select Fast Travel. This will teleport you quickly to that location, and will typically bring any follower to that location as well, regardless of where they were.
If that doesn’t work, look in your house, or the spot you originally encountered them. If they’re not there, try to wait or sleep for three days. If you left your follower waiting somewhere, they will stop waiting on you after three days and return home.
Unfortunately if that doesn’t work, it can mean that they wandered off and died, and hopefully you have a saved game before that point.
Remember kids.. save early, save often!
