Ok I think I figured out the issue?
There was a mod being used in order to pin the server as always available upon installing the modpack, but this server by default cannot have a name. The default configuration for DH is to save the location of LODs for a server in a folder based on the server name, but because it didn't have one it just didnt make the directory from what I can tell?
The issue was fixed after flushing everything out and reinstalling basically everything and not using the server browser mod that puts it at the top.
