Diagnose a blocked base before moving everything
Adaptive Measures added clearer Moonpool size feedback; Buddy System lists objects blocking construction. Use those messages to isolate the cause before refunding a whole base. Keep useful equipment in ordinary storage while you make changes.
A visible generator or transmitter beam alone does not prove the room is supplied under load. Visit the base-power guide for the connection and consumption checks, then return here to finish storage and expansion.
