agree totally. this needs to be kept in the forefront of all the other glitches. this is hands down the single most important glitch they need to work on. I have the first patch, made the game run WONDERFULLY compared to launch...I just want my old save files back.
I encountered this glitch for the first time a day AFTER the first auto update (patch, whatever you want to call it). This issue was NOT fixed by that update. I don't think people realize this isn't fixed, because if you start over you can play for like ten more hours without it happening again. If Obsidian/Bethesda do think the first update fixed this issue I would think they would make some kind of statement about it on these forums. They haven't. This is all they've ever said about the issue,
"On consoles, we are aware that a small group of 360 users are seeing a DLC warning which is preventing you from loading save games. We are absolutely looking into this bug now, along with other reports of save game corruption. It is our highest priority right now that we find out what is causing it. In the meantime, we recommend you save often, and revert to an older save if this occurs."
