0.12.2 same issue on android 4.2.2 ASUS ME173X with a survival world made in version 10.5. I can pretty reliably continue down a long tunnel I made under some ocean and be pulled out and placed in a boat which did not exist previously. I always take the boats back to a chest for storage or use them as furnace fuel, so I never have unattended boats out in the world. Ocassionally I can be pulled to another new boat while in the first boat as grubbbee describes, but I don't know how to make that happen. The bug did seem to start occuring after I first started using boats and I was teleported from one boat to a boat which had been left (so with the second boat I ever created). The way I reproduce the bug now is different slightly in that it creates new boats.
