appdatacache.cpp (311) : Assertion Failed: !"Implement me"

[Hovercat]

No matter what I do to my server, it will end with the line:

Code:

appdatacache.cpp (311) : Assertion Failed: !"Implement me"

and the console will become unresponsive. I'm out of ideas, I don't know what to do. I tried to add a new client to Mani via in-game admin menu and the server crashed. That's when this started happening. I tried disabling Mani, but it still ended with that line and my server refuses to start. I'm in deep need of help.
