I bought this plugin last month & couldn't get it to work. I read the comments about editing the config. Sat on it. Thought I'd check back for an update.
There has to be another solution. Maybe it conflicts with other plugins?
1.) Place a generator
2.) Look at it
3.) Type /setharvester
Nothing. Please understand how frustrating this is. There's no check, no message, no nothing. I get a message for /setoutput but your other command has no messages when it doesn't work.
