We have observed exactly that phenomenon on some Canadian modules that are a couple of years old, but connected to a string inverter. We used an IV curve tracer to test all of of the modules and they tested out fine. That system actually has an expansion with Suniva modules and the Canadians with the strange cell patterns actually tested out with a better observed vs. expected ratio than the Sunivas, which do not show the worm-tracks on their cells.
