Trying to port an old tekkit map over to FTB Ultimate, but no matter what I try, the world always crashes. If someone could point me at a good spot for free hosting, I'm willing to upload a world save for others to try. My kids did a lot of work on this map when we ran it as a private server, and I'd love to surprise them with it again. I noticed Yogscast was able to port their tekkit server over, but I keep getting "exception in world tick" every single time. I've even tried the old hardcore world trick of recreating the map with the same seed, and copy/pasting in the region and data folders, but that doesn't work either. ANY ideas would be loved and appreciated, thanks.
