I tried to put flans mod on my modded 1.7.2 server and it didn't work. I put the flans mod jar file in my mods folder and I had flans mod running on my server, but I had no content packs. I want to get the modern weapons pack, parts pack, and maybe the WW2 pack. I tried making a folder in the server folder called Flan, with the content packs but that didn't work. If anybody knows how I can use Flan's Mod on my server let me know. Also I am on a mac. Thanks for the help.
