I've got a server hosted by orbitblade.com and I've got Tekkit 3.04 running on it okay. However, I deleted the world and had it recreate a new one once I got the mod installed, but I don't think it's spawning any of the Tekkit resources.
Is there some kind of special server setting I have to put in the Gaming Control Panel on the server to get the new levels to generate the proper stuff?
All the other mods seem to be working just fine in-game. I just can't find any Copper, Rubber Trees, Oil, or any other resource from Tekkit.
