Possible bug on level 903

Playing level 903 I got to a point where I needed 2 more cherries, but there were none onscreen. I played my last 10 or so turns, plus 3 x 5 turn extensions, but no cherries were generated. Had to quit, started over, and won easily.

Additional details: had 5-win-streak bonus active, plus had all three boosters selected at the start (first two on timer, third manually chosen)
