If I were you, I'd post a link to here in the "Ask the Developers" forum.

I can understand debug only saying 8 lights, cause there is only 8,
AT ANY ONE TIME. Check on Stromausfall's post to understand that.

If you are relying JUST on that number, dont do so, is a deceiving number.

But Id try posting a link to here in the "Ask the Developers" forum.
There maybe something in your code that is stopping the engine from doing
its "automatic switching lights on and off" to get past the 8-light limit.
