Wow...just when I'm all excited about my 14th hour into the game, completing quests, leveling up, only running into the occassional glitched rad scorpion half buried in virtual sand, I run into absolute gaming horror. While returning to the ncr mojave outpost, i get my free repairs by the trooper and im about to exit building ...game locks up. I figured it may be a glitch with opening my menu too many times while in that location, so i start up again. Once again, crashes as i try to exit building. 3rd time. I manage to exit building. Right in front of me, somehow, like a slap in the face, is the tail of a radscorpion protruding from the ground, obviously alive...reminding me of the semi annoying early game glitches i encountered. I walk 15 feet...and game crashes again. 4th time, game crashes while trying to fast travel out of there. I reset my cache everytime...soft resets, hard resets, @#$%% semi resets....obviously not helping much. If anyone responsible for this fine craftsmanship manages to read my post, thanks for taking care of your loyal customers by sticking a virtual radscorpion stinger up their @$$%!

I've been posting all day about a similar problem. Mine began much later in the game but it was happening anywhere on the map within a few hours of gameplay saves, and instigated by combat. At least I am not alone but I have had to hard power off over a dozen times in a row (a big spank to the xbox hardware) all of last night and today. I gave up after trying one of 10 previous saves. I am currently unable to play. I think I will call this my new FO game and treat forum threads as quest lines.
Anyone for a game of Zork?

What do you mean by "free"?

I had this from the start... *spoilers* just after i hit Primm and went to the Mojava OutPost i had a quest to kill some Fire ant's... half of them was stuck in the walls and svck... but i could cope with that... even cope with gang leaders hiding inside buildings and shooting at me and i can't kill them either, but the worst one is i lost boone and i've just lost 46 hours gameplay, because my save file is no longer there! and i look to resolve it and the best option i get is to revert to a old save which is 27 hours long... oh joy lol guess it teaches me, non the less the glitches svck the bugs svck but the game does not
