IllegalArgumentException: bound must be positive
JulieCooper opened this issue · 1 comments
Getting a server crash whenever a player attempts to join the server. Doesn't always crash the server though. Seems to be the result of a negative number being fed to nextInt on line 353 of SpawnerSystem.java. Is this related to the new 1.18 world heights now allowing negatives?

The crash can be replicated with an empty spawn.json and as much as a single spawning rule in spawner.json:
[
{
"mob": [
"minecraft:zombie"
],
"persecond": 1,
"attempts": 1,
"amount": {"minimum": 1, "maximum": 4},
"conditions": {
"dimension": "minecraft:overworld"
}
}
]
