So I was thinking.
Why cant we move mine supports around?
Obviously Removing a support that isn't completely covered by other supports will cause a cave in damaging all supports effected.
But why not allow us to build the mine support and Stockpile them. (Not in an actual stock pile but lay them to gether like stockpiled tree logs)
When they need to be used they can be lifted and then put into place
This way we can take the temporary structures down once the tower caps we plant mature and use them elsewhere in the mine. :3
