ok im not even 25 % through the storyline yet, and I was saving fine until I got blown up on my boat now no matter what new mission i select or where I save at my safe house or bus or whatever if I try to save over an old file or create a new save it says it was successful but it doesnt show up in my load list and takes me back to my previous save at the gun shop before I had done my first apr mission last night and was on my way to kill the police chief when my boat blew up but i had saved at my safe house before that but it disappeared. i cant figure out which button deletes old saves (like from the beginning of the game) but its not like I can run out of space with 13.8gigabytes left on the harddrive so that shouldnt even matter plus my save from last nite was showing up fine then and this morning but like i said after i got blown up like 10 minutes ago it disappeared....

No i cant do that either, wont let me. Lucky for me it was a rental. would a different rental work? Is this one of those save glitches i heard about?
