i have been in 3 diferent jungles and i hasnt find any gorrilas

"Lupicus" posted a solution on discord that seems to work for me. Edit config/alexsmobs/gorilla_spawns.json to:

{
  "biomes": [
    [
      {
        "type": "BIOME_DICT",
        "negate": false,
        "value": "overworld"
      },
      {
        "type": "BIOME_DICT",
        "negate": false,
        "value": "jungle"
      },
      {
        "type": "REGISTRY_NAME",
        "negate": true,
        "value": "minecraft:bamboo_jungle"
      },
      {
        "type": "REGISTRY_NAME",
        "negate": true,
        "value": "minecraft:bamboo_jungle_hills"
      }
    ]
  ]
}

Same here. No gorillas spawning at all. In SP, that is.

The "SpawnBalanceUtility" doesn't seem to find them either, btw.

Same here, the uility didnt find gorilas, cave centipides are gone too
