Hello,

The plugin has some issues, please try removing the json file and reload the plugin.
I'll take a look at the plugin when i have some time.

Hey, I have trouble with Stacksize!

It's not generating the json script while it's inserted on the oxide plugins folder.

I don't really know what happened I tried reloading the plugin, reinstalling it but nothing.
iv reloaded the plugin 3 times and still cant get a json file
Did you check your oxide/logs for errors? Are you trying to use this plugin on Rust? It's only for Hurtworld.
