Boat bug :(

When I am out at sea on a boat, sometimes the MCPE app closes and kicks me out. When I log back in, my boat is gone and I am stranded. It happens almost every time. Today was terrible, I had my four cats on two boats with leashes while i took the lead boat. The game crashed and I lost the boats, leashes, and cats. Please solve the bug, I wish my cats didn’t disappear forever. Thank you.
