I just got a fresh install of the newest version of IC2 on my linux server. I'm not 100% sure that I did everything correctly, but I can craft some IC2 recipes, so I'm assuming it's generally working on both the server and my client machine. However, I haven't found ANY rubber trees, and I've definitely explored enough chunks in several biomes that I should have found at least one by now. It's possible that I'm just really, really, unlucky, but I'm wondering if it's possible that I've managed to screw something up in the installation that's making it so I can craft the recipes but that it hasn't modded the world generation, so I'm getting vanilla resources only. I haven't done any real mining (I like to set that stuff up near some rubber trees, or at least get a couple saplings first), so I don't know if the world is generating copper/tin/uranium or anything else that is IC2 specific.
Anyone else come across this problem?
