So, I've done almost everything possible in Fallout 3 and have been storing all my goods, etc. in various containers in my Megaton house. I disabled Wadsworth back at the first part of the game because he was so annoying. Recently, I made another trip to Point lookout to obtain more stuff, and when I returned to Megaton, Wadsworth had been activated and all the stuff in my lockers near the door and in my refridgerator were gone. I checked all the people and locations in and near megaton for the goods, but they were gone. In this game I am level 30 with the Messiah reputation. Has this happened to anyone else? BTW, the person who used to give me things - quit, and treats me with distain. However, my karma is high. I just can't figure this out.
You just encountered a somewhat rare glitch that causes the containers in the Megaton house to reset, making your stuff disappear.
Hopefully you have a saved game from not too far back - reloading that is the only way you'll get your things back.
