I have a world that I was playing on as a server running locally, and everything was going great until I tried to update the Tardis mod, after which I get kicked from the server every time I log on with the message "A Fatal Error Has Occurred." I tried uninstalling the Tardis mod completely, but that doesn't seem to have done anything. Oddly though, if I move the world to my "saves" folder, it works fine! But if I move it back to the server folder it does the same thing again. What in the world is going on? I'm not using any official modpack; it's my own collection. I don't know what log file(s) to show, as the game doesn't actaully crash, and the logs I've seen don't say anything other than "Player disconnected."
 
Is this the right subforum to post this? I wanted to post it under Tech Support, but it asked me specifics about what pack I was using, but since I'm not using an official pack I didn't think that was right.
 
Never mind, It wasn't the world after all. Any world did the same thing. I reinstalled Forge and the mods and now it works. Weird. :/
