Dear Mojang,

When you jump on a boat in water for a long time the game doesn't count that you landed on a block and thinks your falling in the air, then when you jump off the boat onto a black it counts the fall damage and you take damage. The longer you jump the more fall damage. I think that this might be an easy fix just make the boat stop fall damage count so that it doesn't think that you are falling. Please fix this sometime in the 1.15 snapshots. Thanks for reading!!
