this problem is still in 1.6.2
Was this posed to get fixed in 13w05a snapshot.
Because it's not fixed in that version.
Re What do you mean...
Think that you have 5 or longer block long water stream and the final flowing water block is above an empty block (water automatically flows down to it ).
Then you drop an anvil to it.
An example X=anvil placement 0=solid block Y=water source block D=flowing water block A=air block.
top layer:
AAAAA
AAA0X (block to put anvil next to )
AAAAA
2nd layer:
AAAAA
YDDDD
AAAAA
3rd layer:
00000
0000D (the anvil falls to the water block)
00000
So this I mean.
yeah, it's still in the game
