Even thought it is a very bad evaluation of the position, this is not a bug.

XG, when going through the ply use 1-ply evalution to pick which move is made. Here it happens that 1-ply make error on allmost all replies. for instance after 6/4 2/1, the dice 21 is played 18/16 11/10 by the 1-ply, while 3-ply plays correctly 11/8. the 1-ply move turned to be a 0.168 error!

The Dice distribution dialog used (in version 1) to show the move pick using the 1-ply. Version 2 is now showing the move based on a (N-1)-ply evaluation. In other word the equity of a N ply in the analyze is calculated differently than the one in the dice distribution.
