Slog

You should move this post over to the Tekkit bugs forum. While you're at it, check the stickies for instructions on where to find your log. It's unlikely that anyone will be able to help you without a log.

I really like how the fence posts ended up being useful after all.

Re: TechBlock 0.5.0 + Hardcore & Tekblock 0.1.2 Derp! I was so focused on that stone block, that I never though to look the other direction!

Re: TechBlock 0.5.0 + Hardcore & Tekblock 0.1.2 Is Sandstone Isle hidden? I can't see it from the starting island. Also, is the single stone block at bedrock level directly below the spawn relevant?

Oh no! How can I But there were a few lols.

...amazing... Is it a secret system?

As Zebrin said, some mods are installed directly into the modpack.jar. I'm pretty sure NEI is one of them. That may prevent you from turning them off with the ModLoader.cfg file (or from the launcher, which really just opens this file). In principle you could edit the contents of modpack.jar to remove these mods, but unless you really know what you're doing, you'll likely break it. If anything, you'd probably be better off building your own modpack.jar by starting with a clean minecraft.jar (from version 1.1) and adding modloader, modloaderMP, forge, and audio mod to it yourself (plus whatever else I've inevitably forgotten). In other words, I'd leave it alone and just hit 'o' to hide NEI.

Really? You delete your existing one, and download the new version. ???
