Fallout 3 - Problems loading NPC's

Hi,

Recently got Fallout 3 and started putting the hours into the game, however after about 15 hours or so of playing I started to get the game not loading characters correctly in Megaton, characters that only have arms and nothing else, or just getting 3D silhouettes. The game also became really laggy and started crashing repeatedly. I saved repeatedly and pushed on with it and now for some reason I'm not having any problems, but don't want this to continue to be a problem later in the game. Anyone else had anything like this happpen?

Nothing but a glitch, nothing to worry about.

Think I've cracked it, Bethesda games apparently clog the 360's memory up, & I had been playing for 5 hours or so! By returning to the dashboard, restarting the game & holding the a button throughout the black screen, untill the game starts (ie untill the loading screen comes up) means that the system clears the cache & releases lots of memory. I assume this works for all games & could be a good fix for many problems & glitches.itsdan
