When you look well at your launch box, you may not see the same thing that a camera (or much younger eye) may see.
A neighbor is having "low heat" issues with new glyphs, and my naked eye, looked and saw everything was A-OK in his trench area...
naked eye sees approximately what the computers built in cam sees.
I took a better look using a digital camera
The moral of the story being do not always trust your eyes!
That looks suspiciously like the results of aggressive cleaning.
