I attach a screen shot which documents a strange situation. During a tournament, I had to await the AI players' rounds to finish before I could play the next round against an AI-player.
However, when the black ball suddenly comes to rest in the position in the screen shot, none of the AI players is able to direct the cue ball in its direction. Instead, each at his turn sends the cue ball directly into the pocket above the black ball... That you see both players named "Sally Silver" may have to do with my speed-setting, as I want the AI players to finish their games quickly during a tournament. And I cannot control which picture the screen-capture will eventually produce (on several I could not even see the cue-ball), so I let the AI-players continue their dumb "shoot the cue-ball to the pocket" game and took many screen shots to compare.
I see, now, that obviously the cue ball was not pocketed but just missed the black. Sorry for the initial false report. The result remains the same, as the game will never terminate.
