The bug I found is with the boats in Minecraft. They lag sometimes when you is traveling with it. If you drive max speed and your about (20-30 blocks) from shore. It will break and you end up far from land. When you get to the shore. Wooden planks and sticks is laying there like if you crash normaly. If you try to drive slower and got closer in to the shore, when you get out of the boat, you still end up far from land. (about 20-30 blocks) but the boat is laying close to the shore Unbroken. But you can't get in to it again and you can't punch it so you get the boat item. It just lay there useless. You can't push it away. it just stands there like a solid block. This could be the same problem with minecarts and horses but i haven't tried. Please fix it.
