Slic3r generates gcode that retracts but doesn't advance :S (2 replies)

If I have retraction enabled, the filament is pulled back but then not advanced to the point it started at. If I disable retraction then the gcode is fine.

Here is the start of the gcode and a small bit of the generated code:

Has anyone fought this problem and found a solution?

Trying to get an i3 derivative tuned and ready to hand off to the college.
