[Minor] Positioning of Plastic Bugs inaccurate

[daemotron]

This one is really minor, just a visual thing without impacting functionality:

When moving the plastic bugs at the speed indicator back to the beginning of the scale, the position of the bugs depends on the last bug moved, not on the first one. Think as if the bugs were numbered one to five, with one being the most left, and five being the most right when all five bugs are moved to the beginning of the scale. Now move all five bugs out of position and scatter them. If you now move bug number one back to the beginning of the scale, it will move only until the position where previously bug number five was. Now move bug number two back, it will take bug number one's previous position, pushing this one to bug number four's original position, and so on.

I tried to record this behaviour in a simple video capture; maybe this helps illustrating:
