The 6 is the ID for Omnia. FTB Ultimate Reloaded is 36. Or just update the launcher, seems to be fixed in the newest version.What filetype is this intended to be? I downloaded the Linux server for FTB Ultimate Reloaded with that 6 in the path (https://api.modpacks.ch/public/modpack/6/38/server/linux) and am not sure how I am meant to open it. It doesn't appear to be a .zip or text file.
