I found two bugs in the game

bug1: When two "/fill" commands are executed in the same area in turn, the effect in the "bug1.png" diagram is produced. The correct result should be all lava.

/fill ~10 ~ ~10 ~ ~ ~ water

/fill ~10 ~ ~10 ~ ~ ~ lava 0 replace water

 

bug2: In the "facing" part of "/tp" command, the angle feedback of vertical perspective is wrong. For example, the "/tp ~ ~ ~ facing ~ ~-1 ~" command was executed by player,the correct execution results in players looking down at their feet. But the execution result of the game is, looking slant down, the effect is shown in the "bug2.png" .

 

We hope mojang can fix these bugs in the next version,Thanks.
