I lost connection a few days ago while privateering, and when I logged back in, there were still people on my ship. So I teleported back, and found myself high above the ship, while it was sinking. Then, I was somehow blown backwards and ended up swimming away from the ship sideways.
Finally, I was teleported back to the ship as it respawned, and found myself in yet another glitch. This time, if I pressed the up arrow, I would face the camera behind me and run backwards, but I would move forward. If I pressed the down arrow, I would walk backward while facing backward. I surprised everyone when I took the helm, because apparently they couldn't see me. Also I took the helm normally, but I looked towards the back of the ship. I haven't heard of anything like this, but it was pretty weird. Here are some pictures I got:

Not a very good picture, but you can kind of see me at the helm backwards:
