So, I got a modpack going, and it's about half done. I just need to do some tweaking. It works perfectly in MultiMC, but I upload it to Dropbox, and re-download it via Tekkit, and it crashes. I spent half the day uploading that pack over and over, mainly due to forgetting something, and having to fix it. It takes almost an hour to upload, and I'm getting pretty angry, fist through my laptop angry. I need help.

Night Terrors
I uploaded the console log. That log was taken after I removed LiteLoader, and Voxelmap, as I think they might have been one issue. They were obviously not the right issue.
