Yeah their chunkloader is kinda messy. Not sure if there is a way around that as we are doing things the correct way, we are even identifying our chunk loader by our mod, if they are loading the ticket as well something very wrong is going on. Send the issue their way and see what they say

On a couple of FTB videos there were remarks that the FTB chunk loading didn't play nicely with other chunk loaders, that's why the Railcraft loaders were disabled in Infinity Evolved.
