I try not to respond unless I've read a thread carefully.
I'm sorry that your game is broken. You didn't mention how it was broken, only that trying to continue the Civil War questline breaks it.
Having said that, there's an element to their prioritizing that I neglected to mention: bug frequency. How many others have experienced the bug you are (formally, not informally)? If it's a small percentage of their users and a particularly difficult fix, is Bethesda going to see a positive ROI on the patch?
I empathize with you, but I don't believe that Bethesda should halt planned development to correct issues that relatively few of its users are experiencing.

Despite the fact that you carefully read the thread, let me point out this post...
Oh so your one of those guys who tests what I program...
Don't think I don't know how a software company works, I do. You likely would not catch every bug, but my friend, there are BIG BUGS IN THE GAME. What part of that don't you understand? Go here: http://www.uesp.net/wiki/Skyrim:Quest_Timing, the UESP wiki, read the very last line. That problem is still not fixed! Why?
Oh and BTW, Bethesda has had the benefit of 6 months of millions of beta testers, yet big bugs still exist. No excuse for that.
Click the link. The Civil War quest line is bugged for A LOT of people, not just a few of us. Other than that, again, I agree with what you are saying, they have to prioritize because of the shear volume of bugs, I'm down with that.
BTW, I can give you a couple of examples of what happens after I progress too far in Civil War...
1) No longer get dragon souls
2) Can't receive many words of power
3) Dialogue sticks and I don't receive rewards
4) Can't place quest items like lexicons on their holders to advance a quest
Just a very few of the problems.
