I can see both sides of the argument.

If she was running from 1st to 2nd overslid the base and was tagged out, she achieved 2nd base negating the force play. Then it becomes a timing play - did the runner score before the tag or not.

In the OP, she is assumed to have touched the base when passing it and this would have been an appeal situation based on defense noticing the missed base. But she realized the miss and went back to touch. Sliding in and (assumedly touching the base) removed the appeal possibility. Oversliding and perhaps losing contact with the base by her fingers or standing up and losing her balance to the first base side of the base and her foot lifting up off the base while being tagged out is a tough sell for me to re-instate the force play. If I didn't think she was actually trying to return to 1B, this is where my logic is apparently in conflict with the rule.

But I don't make the rules, only try to understand them and rule accordingly.
