I don't know if anyone is interested, but the current powered workshop script is full of little bugs.
Everytime I look through it I find something else that is slightly wrong, and/or can rarely fail in some weird way.
I did not make a list (I was too busy working on my own powered workshop system for Rubble), but here are a few I can remember:
The drill will not extend into open space (but it still takes your items).
The drill leaves the wrong tile behind when retracting from a soil layer.
The sorter cannot handle item subtypes (AFAIK, there is even a comment about "getting it working"), but subtypes are listed as options. (my sorter handles them fine, so look there for how I did it if needed).
The whole thing is one giant, hard to manage, rats nest. Ever heard of modules?
