This occurred in today's Hawaii vs. ND State game, in the Tuscon regional:
ND State batting in bottom of 2nd. 2 outs, 2 on. R1 at second. R2 at first.
Ground ball directly towards F4. As she's fielding it in the baseline, R2 crashes into her about 10 feet before reaching 2nd base. Both F4 and R2 fall down. Umpire makes the "safe" signal indicating no Int, presumably because in his judgment, the ball reached the fielder before the collision occurred. In the confusion, F6 picks up the loose ball, and tags R2 before she could reach 2nd base. Umpire calls her out. During that time, R1 is racing around and clearly scores BEFORE F6 applied the tag.
Result: Hawaii Coach Coolen argues the non-call and gets tossed. The 3rd out was made at 2B. Players leave the field. But they allowed the run to score because it occured before the 3rd out. Why? The out at 2nd was the 3rd out and was a "force" situation. This should not be a "timing" issue, should it?
