Network Group is NULL (Oxide)

At the moment, a wipe is underway on my servers. I installed the plugin on two servers, and fairly soon afterwards, both restarted for the first time (the plugin loaded initially), and the first server went offline straight away. It was a standard boot-up; it said the DLL had loaded, but the server did not appear in the server list as expected. Then, during server startup, there is an entity verification stage. As soon as this began, the console was flooded with messages stating that ‘XXX[000000] network group is null’ (or something similar; I can’t recall the exact wording). Consequently, the server froze at this stage, and even after 20 minutes had passed, it still wouldn’t boot any further. As soon as I deleted the DLL, the server started up without any problems.

And just today, a little later than the first incident, but exactly the same thing happened on the second server. Once again, deleting the DLL solved the problem.
