Don't tell me that you've never lifted a

to conclude that you've never worked on a PCB :-)
I've lifted my fair share of tracks (possibly more, just natural greed I
Once or twice I've had to put down wire to make up for my clumsiness,

And just for the record, I have not actually lifted a track. The track
damage is strange and I am not entirely convinced it was me because it is a
little distance from the pin, perhaps 5mm away and it is a break in the
track. It looks like I could have let the iron slip across it, but I don't
recall that happening, and the break seems too wide for the size of bit I
was using. Is it possible there might have been a latent track defect that
the heat from the iron revealed?
