For future refrence, Redmew'sDiggy scenario doesn't work on 0.18, the walls will not support the cave. We had to stop the server for now.
Also, dear Klonan, I noticed thtat the miners (slaves) mine a rock when there is resources beneath it. I have noticed the change in the control script. I remember having to modify your targeting logic to fix this.
Because, in Diggy, If a rock is mined by your mining drones, It doesn't trigger the script correctly. RedMew probably didn't anticipate something such as your mod.
Have a nice day, Mister my mods are awesome.
