After investing 2 times into the armor and weapons caravan, the armor guy (Crow) is stuck in Megaton. Waiting or doing stuff meanwhile doesn't help, he won't move to the next location.

Does anyone know how to fix this ?

Are you looking to purchase Crow's Eyebot Helmet from him, through the maximum investment of his caravan? If so, shouldn't you be able to purchase it from wherever his location?

Or do you just want to get him out of Megaton, so that your other favorable caravans will come through? If so, I'm just going to note that other traders voyage to Canterbury Commons, Temple Of The Union, Agatha's House, Paradise Falls, Arefu, Evergreen Mills and Rivet City, if you wanted to buy things from them instead. Don't have to worry about those vendors leaving their locations, as they're probably stuck like Crow is.

As i said, they should be moving aprox. every 2 hours. So i don't have to search for the right caravan.
