The APB Reloaded blog has been updated with new information about upcoming patches over the next several days. It appears that a nasty bug has landed in the 1.50 patch that has caused some serious crash issues for players. Developers anticipate several patches over the next few days to mitigate the bug and other issues that have cropped up. These patches will help lay the groundwork for the upcoming open beta.

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.
