When I try to make zombies with twice more hp, they are spawning with 40, 80, 160, 320, 640, 1024 instead of 40 only.
spawn.json:
[
{
"dimension": 0,
"mob": "minecraft:zombie",
"seesky": true,
"result": "default",
"perplayer": true,
"maxcount": 100,
"healthmultiply": 2
},
{
"dimension": 0,
"mob": "minecraft:zombie",
"result": "deny"
}
]
potentialspawn.json:
[
{
"dimension": 0,
"mobs": [
{
"mob": "minecraft:zombie",
"weight": 100,
"groupcountmin": 1,
"groupcountmax": 5
}
]
}
]

bump

Try to add 'onjoin': true

to spawn.json?

nothing changed

yes, in your rules

[
{
"dimension": 0,
"mob": "minecraft:zombie",
"seesky": true,
"result": "default",
"perplayer": true,
"maxcount": 100,
"healthmultiply": 2,
"onjoin": true
},
{
"dimension": 0,
"mob": "minecraft:zombie",
"result": "deny"
}
]

Show me the updated rule file

Also I noticed, that every mob spawned with an "egg" has right amount of hp - 40

Weird. I'll investigate this later

Thanks anyway.

I've found the problem. This thing is happening only in singleplayer, whereas on dedicated server everything is fine. Sorry for wasting your time.

Hmm that still points to a bug though. BTW, which version of In Control was this?

incontrol-1.12-3.9.16

I'd like to reopen this as It should work on single player too. For you the bug is fixed but not for me. Thanks for reporting.

I am not sure that this will help, but I've noticed that mod on dedicated server works incorrect too, everything is fine for me, just because on the server I have 1.12-3.8.0 mod version.
