When I have had track day tires go off (I have always used Pirelli's) I have had some sign that they were going away, like an unexpected slide or push. Bridgestones may have different characteristics. I don't think you said for sure, but was this on the first or second lap of a new session? Tire warmers can let you get up to speed much sooner than running on cold tires, but I doubt that your tires are at maximum grip levels on the first lap out, even with tire warmers. Glad there was no serious damage done.
Don't confuse me with facts, my mind is already made up.
