I started playing survival mod, and I planned my base in a mineshaft, so to keep me from dying and respawning at the beginning point I of course set a bed, when I decided to change the location of the bed, after I hit it, it just split into two unique white beds, both functioning, and it is not a lag (I exited and entered and it was still there).

I don't mind that at all, but I bet it is considered a bug?
