Crashes
I believe that is a known issue, and they are still working on getting MQ2 up and running correctly.
That seems to be what is being discussed in chat right now. It is also what happened to me this morning, so I am just taking it as a symptom of not yet being release ready. Tha autologin seems to be especially buggy if you are using that.
That being said, when I get a chance to test, I will check if it will load with no plugins to see if a clean insertion is even possible currently.
