I think i found out what happened, Its very lucky but i think you got a random scene where the pink doll is already asking for her ball back. When she got into the hide and seek cutscene and you presented her with the ball, it interrupted the hide and seek and instead did the "Get my ball" cutscene, essentially skipping a large portion of the run. You can still see the "Let's go" dialouge from the hide and seek cutscene, but no dolls. I think that is what it is, i could be wrong. Now that i watch the video again, the dolls are still scattered around, at 22:50, in one of the spots the dolls can be in, right by the packaged doll near the shelf, you can see a glimpse of the green doll. Very interesting

Is not pressing shift a new strat?? I need to try it!
