My dupe is stuck and task is looping

Happens at my game too.

It seems the problem is that the dupe can't decide where to get the microchip from, since they are not manufacturing it. I get them unstuck by moving them to the storage bin or place that has microchips. But whenever the tuning is followed by another task, they get stuck the next time they have to tune a generator. 

I found a workaround (?). Somehow a unit of microships got split - I had a pile of 1.83 and another of 0.12 sitting around. After relocating them into one pile, my dupe does not get stuck anymore when having a task involving microchips. (The production of new booster packs had also stoped.)

Merge all microchip stacks into one

Thank you everyone so much for comment. Gossmann is fixed now and doing her job again. I found out that my sweepy break the microchip into 0.58 and 0.42 units. I have to demolish sweeper dock to get it out. I hope the dev fix this by not allow microchip to be in form of under 1 unit again (and also add empty storage function for sweepy dock too).
