First of all, unfortunately in the last build there is a VERY annoying issue that snuck in along with all the various fixes (in v.73) that makes it so that you cannot switch districts once you have joined one without crashing.
The crash actually happens when you try to unload the current district, and the bug is related to what happens when 50+ people have custom characters and it gets pushed to everyone else in the district, and there are thousands of people in the world, and then you try to exit your district. We didn't catch it in QA, simply because we didn't throw enough people at testing it for this last build.
We expect to have a working patch shortly to put out there. Of course patching this bug will be hard to 100% confirm until we put in under live load and this patch may even require a follow-up patch depending on what data we see in live.
For the next few days we anticipate having several patches and updates that we release until OB is really ready (and yes - keep in mind - THIS IS STILL A CLOSED BETA GAME! Some of the comments seem to disregard this time and time again, though we are now extremely close to go Open Beta). So again - thanks to all our Beta testers for their patience and their diligent reporting of the issues (or in this case, the automated crash reporting system's reporting of the issues).
Also once we get through the general issues, we will then turn toward solving more specific case issues. In particular issues related to specific hardware configurations (this is where your Beta Application DXDiag is very helpful to us in conjunction with the crash report) where we solve for more and more unique combinations of hardware, and much less frequent crashes (like the first-time startup issue we are seeing at some frequency).
We also were originally going to put out the Item Store today for the current group, but we are keeping it on hold until we can confirm the current general fixes. We don't want people buying things before the general issues are solved.
So now - back into the grind (!), and we will update this blog as new patches get applied. And yes - we are intending to be the most communicative game publisher/developer of all time :). I hope we are succeeding so far!
