By removing the latestbuild file, all plugins running legacy versions have been broken due to the link 404ing when the plugin tries to check it.

Side effect of advancement.

Options:

1. Update to the latest version (13.2 at the moment). Gain lots of new features and security fixes. Highly recommended.
2. Stick to old versions by adding UpdateCheckDisabled: true to the config.yml. I don't suggest you do this.

My implementation of DiscordSRV is a heavily modified of 8.2 (I think?) So I'll take a look at added features and drop them in, I guess

The entire plugin was rewritten for v13. Nothing is drag and drop, sorry. If you have features you want added to DiscordSRV, feel free to submit them via a pull request.
