Does this work on a The Forest server?
Its all installed correctly (i think) and running ok with no errors but on the discord its just showing 0/16 Players even when someone is on the server.

This should work on the forest. The value comes from PlaceholderAPI which gets it from oxide. I did some playing around with it and I also got 0 from oxide while on a server so seems to be an issue with how it's getting player count.

thanks. so the issue is with PlaceholderAPI?

I think the issue is coming from oxide but I'm not entirely sure. Seems like it's not getting the correct player count.
