Following dying via a skeletons arrows while inside of a boat ( can not recall if I was moving or not) I respawned. As a side note I was using the cave world type and my spawn was near a body of water. Jumping into the water I was immediately back on the boat in the exact place I had died and upon trying to leave the boat I was back underwater where I had jumped in. When I went to the surface I was once again back on the boat. I was also running out of air while in the boat. Upon my death. I jumped back into the water and the issue persisted until my next death. Jumping into the water a third time I swam for a bit before teleporting back to spawn. Trying to swim a fourth time the issue seemed to resolve its self. I made my why back to boat and found that despite having moved it while bug was happening it was back to the spot its was when I first died.
