Lerp Skipping - twitching sphere revealed

Left click twice to see the spheres move.

These two spheres have the same scripts on them. For some reason, one (though I think it's random each time to which one this happens) will sometimes skip the lerp and move its start position to the end position immediately. It might sometimes also happen to the other object in the group (it certainly did in the previous demo that I've linked below). Somehow the localPosition is being set to the new end position (without lerping) before the start position gets set.

The script is almost the same as in the previous demo (https://knod.itch.io/twitching-sphere-jig), but the place that the start position is set has been changed so that it happens at the same place that the current time is set to 0.
