We are good too

There's absolutely NO ISSUE with Digicube. Our three nodes never forked, we have the same checkpoint as following.
~/DigiCube/src$ ./DigiCubed getcheckpoint
{
"synccheckpoint" : "fd3626b2e7c2a49021eab5057748393e1bd60ded6903b25955a11ba1 336332be",
"height" : 729912,
"timestamp" : "2016-05-19 18:31:53 UTC"
}
