I'd rank this only as a 'mild irritation' but still think it worth mentioning:
In just the last couple weeks I have started seeing an auto log-out message saying I have been inactive for over an hour. The first problem is it takes me back to the main log-in screen but I cannot select Play (or any other option, there is no cursor functionality). I have to crash out Neverwinter and re-start to get back in. I'd estimate this happens about half the time, the other half I can select Play normally and everything resumes as expected.
Tonight it did it again, with the same 60-minute inactivity message, but the strange part this time is I am sure I had only put the controller down for about 5 minutes, certainly nothing close to an hour.
