How do you disable certain overmap terrain tiles?

[Fool]

I’m making a mod that takes place in a world where the Cataclysm never happens (no zombies or monsters) but robots take over Earth (essentially bootleg Terminator in CDDA). I want to remove all overmap tiles related to said monsters (hives, ant hills). Is it possible to remove these terrain tiles?

Yes, it is. Find the IDs of the overmap specials you wish to remove and make a overmap_specials.json file with the following format:

[
  {
    "type" : "overmap_special",
    "id" : "Anthill",
    "copy-from" : "Anthill",
    "locations" : [],
    "occurrences" : [0, 0]
  },{
    "type" : "overmap_special",
    "id" : "Acid Anthill",
    "copy-from" : "Acid Anthill",
    "locations" : [],
    "occurrences" : [0, 0]
  },{
    "type" : "overmap_special",
    "id" : "Bee Hive",
    "copy-from" : "Bee Hive",
    "locations" : [],
    "occurrences" : [0, 0]
  }
]
