Rise Of Quartron - Robot Parts Not Dropping

For the past three days, I'm not finding the robot parts spawning long enough to drop. Or if they are active, doing damage to them doesn't seem to drop anything. These "activate" for a short while, I attack it, and it disappears, but no drop from it. The only thing working and dropping parts is the Leg Core Gamma (the right leg as u face it). I've switched classes many times, tried different days or time of the day. Is this a glitch / problem / lag effect ? Has anyone else experienced this or know what is going on?

(Sadly i cannot report on git hub.. it isn't working for me)
