I didn't noticed another person used this thread for a random thing, my bad. 🙂
Your config seems right, a value of 3 should give 3x the default stack size.
I've downloaded the version published on Codefling, this is the test config I used.
{
"Blacklist": [
"water",
"water.salt"
],
"Category": {
"Ammunition": 1.0,
"Attire": 1.0,
"Component": 1.0,
"Construction": 1.0,
"Electrical": 1.0,
"Food": 1.0,
"Fun": 1.0,
"Items": 1.0,
"Medical": 1.0,
"Misc": 1.0,
"Resources": 3.0,
"Tool": 1.0,
"Traps": 1.0,
"Weapon": 1.0
},
"Item": {
"explosive.timed": 10.0
}
}
This is the result.. all is working fine.
Are you positive you don't have any other plugin messing with the stack sizes ? Those numbers a bit odd.
