While I was riding a horse very fast (behind me was tame dogs, It was night and I wanted to sleep on a bed) I putted a bed (the dogs was very far away from me). When I putted a bed, in the same time dog teleported yourself into a bed place and the bed has disappeared. I thought that I have lost my bed but When I tracked the bed with the crosshairs and I clicked to a right mouse button, the bed was appear. I also mention that I was making a simple bridge and around me was the ocean. Mayby this was only one place for a dog to teleport to me. The photo below (2019-05-11_14.00.18.png) it is state after bug (before them, the bed was deasapeared and the bridge was shorter of course when I did this photo). This photo is for recreating this bug. The next photo is showing from where I was rding a horse(this is of course the beginning of the bridge).
