Hives are great sectors, but if you house-rule them to make them more of a nuisance, you have to be careful or your players will simply discard them when they find them.Here's something you can try:
1) If there is no Ancient ship or Influence token on the hex at the end of a turn, add an Ancient.
2) If the die roll does not cause an Ancient to move off the hex, and there are less than three on it, add an Ancient.
