Actually, It is too rough to work programming units correctly. There is not enough information of programming in this game. Even I tried in many test cases, I don't know why continuous dropping items doesn't work. I need a guide clearly about programming. Is some calculation(ex. div) problem? What is wrong?... or just bug? I am not sure... I think many players also have simular problems like mine. I mean problems are challenge for programming. Even I do programming in real world as a job, it is too hard lol.
Anyway, I think the core of this game is programming units for automatic factorying. it's why I suggest to make guides clearly and detaily for programming.
I am not sure that this screenshot will help you or not, because it printed in Korean.
Have a good day and happy new year early.
