Ill see if i can add support for this when i get home
Edit: I added it, it will have its own location in the list "Shilo Village" with the option to pick gem rocks. May take up to 48 hours before it is live for you to use however

When selecting not to change tile, you need to specifically select the rocks you want it to mine as well, otherwise it will mine any of that type in the area.
The banking I'm not sure what happened, but I'll give it a lookover. What were you mining?
It would mostly be on the safe tile unless it is running out to pick a new target.
If the break decides to interrupt that, I have not implemented anything as of yet to counter it
