same here, i use that plugin and it stops the damage. and it is decay damage "internal server code"
public void TrapWildlife(global::TrappableWildlife trapped)
{
global::Item item = global::ItemManager.Create(trapped.inventoryObject, Random.Range(trapped.minToCatch, trapped.maxToCatch + 1), 0UL);
if (!item.MoveToContainer(this.inventory, -1, true))
{
item.Remove(0f);
}
else
{
base.SetFlag(global::BaseEntity.Flags.Reserved1, true, false, true);
}
this.SetTrapActive(false);
this.Hurt(this.StartMaxHealth() * 0.1f, Rust.DamageType.Decay, null, false);
}
