Disappearing block bug is still around, seems far more regular though. Anything you do after you've glitched is lost too - so if you destroy blocks using a pick when you relog they're all back but oddly the server keeps your location at log out. I've noticed a couple of ways you can see if you've glitched.
1. Place a torch, if the block vanished you've glitched.
2. Walk into an area you've cleared blocks, if you take damage you've glitched (suffocation awaits if you stay still).
3. Some blocks will "jump" around at random and can't be picked up even if there's space in your inventory.
Most importantly - log out away from where you were mining, you dont' want to log back in and find the blocks around you are back.
It's almost as if the server loses sync with the client, although text chat continues to work and the client allows you to keep playing as long as you stay away from the area of the blocks you're actively removing
