We know you're eager to get all of your bugs fixed, but if you stuff them all in one bug report, chances are they'll get lost or it will just make things more confusing. Try your best to make one bug report per bug, that way you can be as specific and detailed as possible and we can focus on one bug at a time.

OK Thanks, I look for a duplicated, but looks like I was not skilled enough to find it.
I will watch MC-11834 for resolution. The world I had was almost 6 months old with millions of items now gone.
