If you’re unable to progress to the next mine because the game says, “All mineshafts need to be activated,” here’s what you need to do:

  1. Activate All Mineshafts: Ensure that every mineshaft on the sides of the mine is activated. A mineshaft is considered inactive if safety cones are placed around it.

  2. Complete the Level Requirements: Remember, all shafts must be activated to complete the level and unlock the next mine. Double-check the entire mine to ensure none are left inactive.

Once you’ve activated all the mineshafts, you should be able to proceed to the next mine without any issues.
