The same pattern here, the value of the outfield prime isn't recognized at all.

1. Rollout¹ 12/6* 10/6 eq:+0,512

Player: 79,06% (G:9,09% B:0,31%)

Opponent: 20,94% (G:10,70% B:1,07%)

Confidence: ±0,025 (+0,488..+0,537) - [100,0%]

Duration: 48,7 seconds

2. Rollout¹ 18/12 15/11 eq:+0,217 (-0,296)

¹ 1296 Games rolled with Variance Reduction.

Dice Seed: 59890281

Moves: 3-ply, cube decisions: XG Roller

Search interval: Huge

the moves that BGBlitz prefers 18/12 15/11 and 24/20 18/12 are again not even in the 32 moves list of XG but moves like: 9/3,7/3. Making a 6-prime is a 0,300 error??

a plain rollout 3-ply rollout gives:
