Probably the net effect, but I don’t think it should have been happening. We’ll probably find out by tomorrow.
I honestly don’t think those flames were anything to worry about. I have seen a bunch of Falcon 9 landings, and even with those, there are almost always those flames coming from somewhere, lazily licking at the metal.
Those are, I believe, thruster ports, and they have blue focused flames at very high temperature coming out of them when they are being used, so the soft yellow flames couldn’t be anywhere near the temperature the thruster ports are used for.
That’s the way I see it, at least, but...it is true I am no rocket scientist!
