xbox 360, Regarding a bug/glitch that seems to have been around awhile. Explored Karthspire early and solved the 'puzzles' 3 stones and tile floor, upon opening the 'face door' the moment i step through Esbern and Delphine promptly run back to the 3 stones and nothing can get them to move.
The are various 'work arounds' such as using lvl 3 force to push them beyond the door way or at least over that first bridge, or fast traveling to the temple or saving and reloading. None work, or atleast none work for me.
Without a save prior to this point this means the vanilla main quest is incompletable, 90+ hours in, a handful of skills maxed the old fashioned way no exploits used, needless to say I'm slightly ticked off, especially after shrugging my shoulders and saying oh well after the wooden mask vanished from my house (yush i've checked extensivly) or after the bookcases bugged causing half of my collection to disappear.

My question, is this, arguably game breaking, bug which has been around since release and reported many times being at least looked at? There have been numerous patchs and incredible DLCs but no fix for this issue, should not bug fixes be of a higher priority?
