So like most everyone on these forums, I too ran into the game breaking bug of my save files becoming DLC corrupted. After reading the various posts here figured i'd attempt a complete list of currently known / experienced bugs. As people respond to this I'll add to the list, please avoid repeat posting of bugs.

------------------------------------------------
I know there's more so keep the responses coming! I'll also update this and state which ones get patched as that occurs.
some of these are repeats, some aren't:
the game crashed when i opened the door to the mirror field at helios one. twice.
after a third attempt, i made it into the field, and then it started getting choppy and jumpy. that soon ironed itself out, only to have the sound get super screwy (technical term) and sound like someone was hitting mute and un-mute repeatedly. then it just crashed again.
another glitch upon entering that field is that about 10 dogs start leaving the door and piling (heh. dog pile.) up on each other for no reason. the other thing that happens is about 15 barrels fall out of the sky onto me!
the arms raising to the top of the screen thing is still happening.
npc's occasionally just walk knee deep in the ground. which is fun, but then they can't get anywhere you need them to. (example: not too much of a spoiler.. the captain in the office park doing his duty with me as back-up, couldn't get into the building he was heading toward because he was stuck.)
i found a radscorpion pinned vertically to a rock, still alive. it was neat because i thought maybe the legion crucified a radscorp, but then it started crawling down into the ground.
and once out of every.. maybe 15 times, i'll be in vats and my guy won't shoot a single shot, which results in never coming out of vats. he just stands there until he gets shot to death, taking it like a champ. albeit in slow-mo, which looks funny.. but annoying if i'm in the waste and haven't auto-saved or manually saved in a good stretch. i understand a good fix for this is to manually save more, but i shouldn't *have* to rely on saving for a game not to glitch me literally to death.
in the strip.. i confronted benny, survived the ambush, went to his suite, and talked to yes-man. upon taking the elevator to the subbasemant and investigating, i leave to come back up (btw, neither ed-e nor veronica follow me down) and the game crashes..
another new thing as well: npcs are now just falling down whenever i jump around them. although funny, not conducive to a fun gaming experience in terms of pushing the story forward.
