I was playing Fallout 3 again and I got a glitch when I was trying to level up that did not let me select a perk. It "grayed out" the "Done X) option leaving no ability to continue the game. I got NV today and the first time I got to level up this glitch happened again! I deleted my whole Fallout 3 file off the memory of my 360. I even deleted and started over my NV game. I happened again! Has anyone come across this glitch? Is there anyway to fix this or cannot I not play the fallout series on my 360 ever? Very weird this happened in a different game. Is it my system? Seems to be working fine otherwise. Any help would be appreciated. Thanks.
