Ok so I saw the post indicating that OP Prison is no longer supported and is likely to be removed next time someone gets around to it. I guess I understand, it's been glitchy and I heard it is using some unsupported plugins the way it has been setup now which were barely working. How about a reset with different OP Prison plugins that are still active and supported by their authors. I see other servers are still supporting it but they all seem to be running on some different base code and I'm guessing if you reset and used a plugin where the author is keeping it reasonably current with the latest minecraft and spigotMC / bukkit / bungeecord support it's not going to have the glitches and admin overhead the current old code has. eg: https://www.mc-market.org/resources/2801/ I like the mechanics of the current OP Prison. Not a fan of some of the servers that allow more "automatic" mining like autosell or 1 hour of automining etc etc. So if it did get reset with new style plugins at least any options that can be turned on or off should be carefully considered to try and replicate the current style.
I liked the old opprison 2 years back. It'd be cool to have back and be fixed. All the servers are still on the hard drive somewhere.
