It may be good to inspect the feather element and see its position; my guess would be that it is floating up but perhaps out of view.
Note that physics is a simulation; while care is given to try to make runs identical, there are a number of factors that can result in differences from run to run.
There is one issue in 3.6.8 and 4.0.0 that could trigger actions on mouse up being triggered twice on Chrome for Android, so if you hit that then I would re-export with 4.0.1. Otherwise I don’t think re-exporting is necessary.
