If this is printed with multiple models at once, or with priming tower or so, it could be that the nozzle leaks while traveling through the air, and then deposits that blob onto the model when arriving at the edge? If this is the case, printing slower and cooler should reduce the effect (=less pressure in the nozzle, and filament is less liquid), but it is hard to eliminate totally.
If this model is printed alone, without the nozzle traveling elsewhere, the cause must be something else. Maybe settings? But I am not using the latest Cura version, so I can't say anything on that.
I have seen in CURA that the position of the bumps matches the beginning of the outer wall line. I'll upload the CURA project when I get home.
