Dave,

There are two iterations of that, in a somewhat silly attempt to validate that the RETURN was working - or failing. No difference. Irrespective, they've been removed.
The TRIG output goes high and low exactly as it should, when the CHUBB input goes high or low. That tells me the loop is looping. (Loopy?)
After startup, the TWO led routines do work. ONCE.
I can't see anything that is unhappy in the counting, the compiler likes it, and it seems to read ok, it just doesn't work.

What the heck....
