This has happened twice now, in the last 24 hours.
The first time, I was in a pitched battle with some dead things. My screen suddenly went blank (grey), I got a small box that VERY briefly said LOCKING and then the screen went black. I have a lighted keyboard so the laptop hadn’t shut down, it just went blank. No input from the keyboard was recognized or accepted. Not even CTRL ALT DEL.
This time I did a force quit because nothing would bring up a screen.
Second time, I just teleported back to town, was idle for maybe a minute and then the same sequence - Blank screen, LOCKING, black screen, no input accepted.
This time I waited it out to see what it would do. My entire laptop rebooted and after I got back into Windows, I got the loading screen for the game trying to tell me I had been disco’d and then tried to load my game again. Then it crashed to the desk top.
This is new, for me, in the last 24 hours.
I dont know yet if this is a YOU problem or a ME problem, but since it happened twice now, thought I would post it.
