The problem: I can't find any industrial craft ores anywhere on the map.
Events leading up to the problem: I tried to update Minecraft. I made sure to make a backup of the minecraft.jar file before doing so, and then afterwards I copied over my mods. So that's when I noticed that I couldn't find any industrial craft ores. I then reverted to my backup minecraft.jar file, but I still couldn't find any ores.
Question(s): Does anybody know a way to fix this? My brother suggested that I install a map editor and copy everything I care about on the map (ie my house) and then paste it onto a reset version of the map. Would this work and if so how should I go about it? Is there an easier way to fix the problem than that?
Thanks so much guys!
