I added S+ and CKF:R today and it isn't working now, maybe related...
I've tried a few things:
* Restarted client and server
* Redownloaded the mods
* Removed the server side mods (this one works, but isn't the solution I want)
* Validated that the client side mods work in single player
The server doesn't crash, but I am unable to connect to it. I just time out. I'm going to see if I can check some logs on the server next.
