Open Base Download - mym World Downloader mod

I`v just tried to use the world download mod (https://mineyourmind.net/wiki/knowledge/world-downloader/) on the sevtech server, i tested both versions of the mod for 1.12.2 but the server didnt seems to respond to any, instead it returned that the commands were unknown.

Is there another way i can get the chuncks of my base downlaoded?

 

Hi SparedPumpkins, yes i tried with both available .jars on the mods folder (one at a time) and in both cases the mod is recognized by the client, but doesnt seem to actually work when running the command on the server.
