[Bug-gnubg] Cubeless Rollout Bug In New Build?

[Michaeldepreli]

Hi 
Take a look at this :
Use doubling cube OFF 
Use Jakoby OFF
Cubeful checker play OFF.

Analyse Rollout:
0 ply (Only 600 trials but just to demonstrate)

NOV 19 Build Results
0.7010 0.1831 0.0057 0.1383 0.0014 Eq +0.61  (Looks OK)

Latest Build DEC 28
 0.3548 0.2035 0.0057 0.1126 0.0014 Eq -0.2 (I don't think so!!)

If I select 
Analyse Rollout Cube Decision

The cubeless numbers look ok in both builds.
