I did some searching around, and found out that ComputerCraft apparently has a lot of bugs--that it's better to use redpower computers and simply not allow computercraft computers.
I've also found out that in your tekkit server's folder, you should find a "/config/ModLoader.cfg" file. That file should show a list of all mods, allowing you to easily disable any unwanted mod.
However, the file does not exist, and even if I force one into existance, it doesn't get touched by the server. So if I cant disable it through there, where do I disable the mod at?
