There's something wrong, again Saturday's source build:

The dice have been set to 3 and 5.
The cube has been set to 4.

jim_segrave accepts and wins a single game.
jim_segrave wins a single game and 4 points.
The score (after 1 game) is: jim_segrave 4, aintifun 1 (match to 5 points, 
Crawford game).

once again, this is broken.
It's the same with 0 ply or 2 ply evaluation
