My first guess is a poor or low on charge battery. Same thing happened to us during a practice match in Waterloo, as soon as the battery was changed, everything was back to normal. Make sure the battery is completely charged, you might be using up a completely charged battery every match.

Another possibility is a screwup in the communications between the OI and the RC, for which you will need to confer with the Innovation First.

Our programmer swears that he didn't change anything in the code.

And last and the most important thing is to keep trusting your programmer, we are all good people.

Take it easy,
