Dear Minecraft creators, I have a Nice amount of bugs to report,

1. "Water Block" Whenever you place a water bucket in creative and also I think in survival is sounds like a block being placed and then block particle (the ones which when you break a block) appear.

2. "Block Lag" in various servers (which are in 1.6.1) have the same lag, The block lag. It's whenever you place a block it dissapears then re-appears. same when you break a block.

3. Sprint- The sprint has a tiny bug, it has a 2 second delay whenever the player tries to sprint...

Thank you for your time,

hojp
ps: Hope this really helped.
