well tbh it's not been that much of an issue (with myself at least). During playing this game i have crashed on an extreamly rare occasion. With this in mind, I think it is fair to say it's not on the top of their priorities.
Imagine if for th next 6 months, they fixed all the game bugs. Ok, you have a no bug game. But then they add content and changes. Guess what, BUGS! They need to fix the bugs as they work along the changes. Otherwise all the work they done before hand is pointless.
I for one am happy with the changes in this patch (cannot wait to try them out ingame of course), and I think picking holes in a couple of glitches here and there is ungreatful and disrespectful to the overhaul thats being implimented here.
