Alright so a couple things:

My previous issue of being attacked by the Legion even with Caesar's Mark stays.

I now have multiple audio issues: Voices cut out, gun noises cut out, the reload sound effect never works.

C'mon, Bethesda, I was going to start over with the first glitch but now the audio glitches make this game annoying to play.

I still cant load my saves after the "come fly with me" mission
The data isnt corrupt! I tried copying it to my flashdrive, along with the caravan pack but i got the same "relies in data no longer available" thing

I turned on my xbox got super happy because there was an update
go to load my game
and BAM

I get cockslapped by Obsidian and Bethesda

Same problem - Caesar's Mark. When I reloaded after the patch all the pips were yorange, so I figured, Yay - fixed - as soon as I was in contact range, they switched to red, one by one. Come ON!!! Hullo - Main Quest anyone? Game is broken...

Yeah exactly what is happening to me. Even with Caesar disguise the dogs and Elite guards still see me and freakin' attack.

Actually, you got slapped by unrealistic expectations. Your corrupt saves are gone, delete them and start from an earlier save or start a new game.

same thing here and every second of gameplay was done AFTER the patch was released so thepatch has not made a single difference to the bug.

Must you go on? Sheesh - it is NOT an unreasonable expectation that the game work, or that the patch fix problems that have cropped up. Are you the self-appointed excuseboy?

Any plans on fixing the Legion thing, Bethesda?
