thegemfitness I checked your config, find it was a bit* hard bcz u’ve sent all config files, then in main config.yml I’ve found you use DropBox..did u reuploaded pack into dropbox as it was regenerated with emojis?
Can u try self-host? Few people had problems with external host which was on google drive/dropbox or on another cloud hosting..
And after that u did /iareload and /iatexture?
Then check log if are not present any issues
When nothing will help from these, try same pack on clean server (IA3.6.3 beta 14, protocollib 683 and LoneLibs 1.0.46
