I have created a drilling platform for the start of the game in SP Survival. The platform seems to work correctly in creative mode (I did not wait for a complete run). In the normal game the script runs but nothing happens except that the drills turn on the spot and mine a small amount of rock within reach.

The terminal briefly indicates that everything is ready to start, too quickly to read everything. Then it starts with "Aligning Starting Position" with no progress. I then tried to see if I could make progress with ‘Set’. Then the terminal says ‘Aligning...’ but again nothing happens. I then tried to start the whole thing, it still says "Aligning" but nothing happens.
