Test 1
What did you do?
Placed 2 Electric Mining Drills outputting onto a green belt while having very high Mining Productivity research level (5373 in the save, but 2391 should be enough if it's just going by the stated mining speed)
What happened?
I see between 23 and 26 ore placed on each ...

Electric Mining Drills don't seem to be able to stack their output consistently like Big Mining Drills; output from them appears to be compressed but only partially stacked despite having plenty of mining speed to fully stack a belt. I wanted to use them in the endgame due to their smaller footprint ...

Almost missed it when searching, but yeah, there are two bots stuck over one of the Jellynut fields (bottom right) trying to place ground, I think they are trying to replace concrete with overgrowth soil and the instruction has gotten stuck, apparently they can't pick up the concrete to replace it.

In my Gleba base, occasionally I see construction or deconstruction orders being ignored permanently. A building scheduled for deconstruction will sit there indefinitely, including being ignored by my personal bots . I've also noticed that the Roboport network reports 19998/20000 Construction Bots ...
