Windows 10 Preview (14295.rs1_release.160318-1628) client crash
Sometimes these things work themselves out, sometimes the push for a new unified code base means they wont.
At any rate, I updated to the latest preview release for Windows 10 build 14295.rs1_release.160318-1628 and the launcher client will crash ~15 into a game every time. The game finishes fine, but once you click that "done" button you have to relaunch. It does, however, leave me with a bugsplat so hopefully you guys are getting these.
