• CPU opponents now continue manually raising the field until a new row arrives when no useful clear or setup is available.
  
• Fixed a case where a field with no legal swaps would not be manually raised.
  
• Reduced pointless back-and-forth swapping by avoiding recently repeated board layouts that produce no clear.
  
• Preserved difficulty scaling: easier opponents react and raise more slowly, while stronger opponents resume searching for clears, combos, and chains sooner.
  
• Independent move choices remain in place. Opponents can still choose the same obvious best move.
  

Manual raising continues to respect stop time and ceiling safety. Online player-versus-player rules and save data are unchanged.
