spawner.json tends to spawn mobs right next to my friends in multiplayer. We're 8 players. Specifying a higher "mindist" parameter seems to lower the frequency of this happening. It doesn't happen to lone players (or at least we haven't noticed), it happens when we're doing something together like exploring or something like that.

We've also seen monsters spawn in well lit blocks.

spawner.json

[  
  {
      "mobsfrombiome": "monster",
      "persecond": 0.5,
      "attempts": 20,
      "amount": {
        "minimum": 3,
        "maximum": 7
      },
      "conditions": {
        "dimension": "minecraft:overworld",
        "maxhostile": 140,
	    "mindist": 50
      }
    }
]

I have to think about a proper solution here
