It looks to be playing correctly. I have owned three Frontiers. Keep in mind that there are two bonus criteria. ABC lanes lite each one vertical. The completion of them horizontally is a different bonus. I watched your video twice and it seems to be working fine in terms of the den of predators bonus lights.

Sorry Matthew, I was confused (which is easily done) Looking back on some old RGP technical posts, it may a cracked solder joint on a header pin.
I will quote one of the posts.

"I put light side pressure on the driver j4 or cpu j1 and run coil tests
again to determine the bad board...pushing one way or the other, I
usually get the coils to fire properly. Then remove the board and
reflow all the header pin joints and check the Molex pins in the
connectors. (most likely a header pin joint as the original board
works) Your decoder is always seeing a zero on a data line that should
sometimes be a 1...your driver board is doing exactly what it is being
told to do, but part of the data is getting lost between the cpu and
driver board."
