This is the circuit from input to the regulator showing where mine was broke at.


The trace from D2 to C2 is underneath the PCB while the trace from C2 to C3 is on top of the board. The soldered thru lead of C2 completes the connection thru the board, however the top trace was open underneath the base of C2 for some reason.

I see, maybe the cap was touching the trace and by the time the green mask was damaged and shorted the trace causing it to break off.

Good diagnostic work! It's satisfying to find those kinds of problems and then fix them. I had an old Korg Polysix synthesizer that had an old NiCd battery for the memory that failed and leaked all over the board, eating up a bunch of tiny traces. I did the same kind of fix, but to about 15 different traces, vias and more. It was a triumphant feeling to get it to all power up again.
