Stripmining Issue (unremovable blocks)

While stripmining for a project I encountered something I did not encounter in 10.5, sometimes blocks are not removable, if I create a group and point them to go to the block they simply ignore the order and just simply wont remove the blocks, of course not being a construction I cant “destroy” either :confused:

PS: I’ve tried adding blocks around it to facilitate access and buildings all sorts of stairs

have you built ladders up to them? if you havent the hearthlings wont b able to reach them.

As I mentioned under the image, I have :confused:

Not entirely sure, but this might relate to an error message I came across where it seemed like some Hearthlings were unable to recognize tasks.
