The only settings I'm trying to change are as follows and nothing is working. The oddest things I get are 0 errors but it doesn't do anything https://gyazo.com/9bf15456adbd5f9faafb2794ba5f7940

uh? you are changing the plugin code and not actually adjusting the config like you should be. also not very clear what you are trying to do actually

I am trying to change the smelting rate the last lines of code you see is what I'm trying to change but it's not working.

You should be changing the configuration under /oxide/config, not the .cs file - never ever change these unless you know what you are doing.

got it thank you

helo im have this configuration no work :(
