Paddling a boat into lava breaks hand.

When you paddle a boat (and boat) into lava on the latest snapshot in either creative or survival, it will destroy the boat and force you out of it and when you get out, your main hand does not show up, and although the left click on your mouse still works (although you have to hold it down for a little bit before it starts to do anything), it renders the right click completely useless. Hopefully you guys can fix this, thank you!
