What other programs/plugins are you running?

No

What is happening?

Snap can't load 3.x versions of BungeeSafeGuard and the commands of the plugin don't work. But Snap can load version 2.6 of BungeeSafeGuard. Steps to reproduce:

1. Install Velocity 3.1.1
2. Install Snap #25
3. Install BungeesafeGuard 3.0 or 3.1
4. Start the server
5. See the error

What did you expect to happen?

Snap can load 3.x versions of BungeeSafeGuard

Seems to be using Bungee's libraries system to load kotlin as a dependency. Gonna have to look into why that doesn't work right now, it should use the same logic as Bungee to load plugins there...
