Which of the following are you submitting this issue for?

• Prison Core
• Prison Mines
• Prison Ranks
• Prison Cells
• Prison Shops

Describe the issue you are experiencing.

When I start the server, the console does not print out that the module was loaded. And when I checked if it was not loaded with the cmd /prison modules, I did not find it loaded.
I tested it on Spigot 1.9.4 latest build & Spigot 1.8.9 latest build.

I just realized you were referring to mines. The mines module is not yet complete.

Do the other modules load?

Yes

Ok thanks
