Bricktrons don't want to dig
At the moment I'm playing Invasion mode.
In the picture you can see that i gave my Bricktrons the task to dig a quarry but they are just standing around and doing nothing.
As you can see, there are enough free stockpiles for stone, iron and brimstone and there are enough tasks, which need this ressources too.
In the most cases I know, that I forget something. But this time I have no idea, what could be the problem.
Thank you in advance, for your help
