I am using the filler from buildcraft and it seems to not work in my overworld base. No matter what size (standard to custom), power (gave it 21k rf/t), or what mode it was on. The block is green like it works but it doesn't. Is it disabled on purpose? Or conflicting with something? Or am I using it wrong? I have no clue. Edit: I'm using it to clear a hole for my underground base
Unfortunately you will need to remove the claim for it to work. At this time we can't keep claims grief secure while allowing them in claims.
There is a workaround I've found where you /trust all, do your filler work, then /untrust all. Is there a way I can type /trust "buildcraft_user" or something along the lines?
