Empty bucket dissapears when try to get water/lava in iPad 2

How do you mean it disaperas, you get a new full bucket? Could you please give some steps so we can reproduce the error?

Yes yes when i try to get a new bucket(full bucket)

Johan i think buckets taking damage because i tryed this again and i lost my bucket in my inventory

Can i record all bugs which i found and send to you?

Johan! i found the real bug

1- get water
2-close world
3-close game
4-open game
5-place water bucket somewhere
6-dissapeared!

The empty bucket turns to water/lava buckets when you get those block, then it goes to your inventory, it doesnt disappear
