Sorry to hear you had to press the restart button, but those who've been doing this for a while that seek out and take in new cuts, well, this is just part of the game. Broad mites are very hard to spot even with a scope. Literally a 60x will only barely make them visible, 100x or more is better for spotting them. But even then, they don't have movement patterns like other bugs and can sit eating for a while so they simply look like a spec of dust. Hit them with Avid and call it a day.
