I've had this happen before but never for more than a few minutes
Until today. I left a server because it was about to restart, tried joining another one and was kicked immediately, now I'm locked out.
GT: iiGray Squirrel
Xbox one

I knew it wasn't just me! I was so worried something was going wrong with my console!
Take note that I have had this happen with other applications and such as well, the biggest thing for me, is YouTube and Dayz.
If I try to switch between them, lets say to eat while watching something and take a break, it will cause the console to make the power off chime, then the screen will go black.
After a few seconds, the green xbox startup splash screen pops up, and the console has hard reset itself.
I'm assuming it's a bug in the actual console firmware, that's conflicting with the game in some way.
I only suggest this, because I can sometimes get the same problem messing around with other games and applications.

@dickjohnson It seemed to me like the update changed the server menu, so that the tabs on the upper right side of the screen actually worked (They added an option or two as well)
All I had to do was adjust those settings to find servers. Back out to main, or refresh, they should pop up.
And the issue is, things that aren't equipped are lost, so it left you your clothes, main weapons, etc.

I had the same thing happen, alice pack and vest were full of full AK clips, boxes of ammo, food water, etc. Almost didn't notice it right away, until I realized I had a lot more stamina.
I collected a bunch of food and water, luckily, but when the server restarted, I jumped back in and it was ALL gone again.
Definitely game breaking for me, been loving this game so much but I won't be able to play until it's resolved unfortunately. Especially when the servers reset so damn often.
