Are there good ways to deal with these kind of issues?
All you can really do there is to carefully scrape the green stuff off the track for some distance (half an inch?) on either side of the break, lightly tin the exposed sections of track and then lay down a fine piece of wire which you've already cut and shaped to follow the route of the missing bit of track. Solder the wire into place on both sides of the break so it replaces the missing piece of track.

By the look of it this needs to be very low profile (as thin and flat as possible) so use the thinnest piece of wire you can find - a single strand from a stripped end of 7-strand would be about right.

Make sure the replacement 'track' follows the same loop shape as the original obviously did, as it is clearly diverting around something like a support post which fits directly against the PCB in that area.

Crossed with Julie.
