A bit late now I suppose, but before you get ready to 'question my intelligence' (which incidentally, makes you sound like an absolute *******), maybe you should actually re-read what Alan took the time to type up. The bug is something they can not reproduce, so providing that there is a bug (and not something that is occuring that Allan also pointed out in his post), there's another issue going on which is going to require a lot more digging. It could possibly be something that isn't even Bioware's fault, such as not up to date drivers, or driver conflicts, etc, etc.
Civility please. @Arijharn, a number of people have called you out on your initial, deliberately provocative and condescending post. So I won't do that again. Let's just make it clear - this issue has been reported, SCIENTIFICALLY AND WITH VIDEO EVIDENCE by people across multiple platforms. So while me on the PC updating my drivers MAY help me in the short term, that definitely doesn't go to the root of the issue.
I noted you mentioned you are a software engineer in another post. As a software engineer, you will know that these "cannot replicate" bugs are actually quite common - often systems are designed to handle a certain path through them, which users can blow sky high. I headed up a QA team over 10 years ago, and I can't remember how many times offshore developers told me that an issue was not reproducable on their end (requiring screen sharing etc to convince them) . Which is why colocation of testing and development teams is actually a critical success factor in large scale deployments.
Similarly, I'm not sure whether BW office test systems fully replicate the varied situations we face in the real world. Therefore, it may be taking them a lot longer than expected to nail this down. What gives me hope is that at least we have gotten their attention and they are trying.
And it's not a matter of expectations - couple of days ago I played with one of my characters who is just 8 hours in, JUST unlocked sword coast, and I brought Viv, Sera and Blackwell, whom I have NEVER travelled before. Wandered around the sword coast for a little over an hour and in that time, no banter at all. Given people who don't have the bug have stated that they get banter every 5-30 minutes, this is NOT expected behavior.
Of course, BW has kept mum about what the expected behavior / benchmark should be, so we are just going by what other players tell us.
BTW, OP was not by Allan. Just want to keep confusion to a minimum RE Bioware employees!
