20220424 - 15:35 - 360R didn't sink into one of the pads. That counts!
I also accidentally used low temp paste on this board, so it's double cursed.
Nr. 7 also had a problem with the 360R resistor, maybe that value is especially sensitive.

20220404 - 19:54 - no tombstones.
Paste for 240 and 360 Ohm resistors required manual rework prior to reflow because of sloppy squeegee action.

I do admit that I swapped two resistors. Might be significant.
