Hello!
After a long time i revisited the maps and wanted to look if everything is alright and guess what... it wasn't.
the Modpack i was using for this map was sadly cancelled and i did not recognize it as fast as it was happening and the modpack wasn't working.
So i sat down and began to "recreate" the modpack and put it on the TechnicLauncher. so here we are, i made my own Modpack for these maps i will post here and for other uses of course too, i will try to maintain it as long as i can! ^^

Installation of HiddenJoker's Modpack:

1.  Get TechnicLauncher here: https://www.technicpack.net/download
2.  after sucessful installation and login to your Minecraft-Account you can either search for "hiddenjoker" or put this link in the search
   bar of the Laucher:
   api.technicpack.net/modpack/hiddenjokers-modpack
3.  Install it and put your downloaded map into the destination of the modpack which you can check when you click on modpack-options
   which is located under the launcher-Options button, then click on the open button, after that your explorer will open and you go into
   the maps folder and paste the world file in the maps file.
   NOTE: you have to extract the .zip file first otherwise Minecraft won't recognize the world.

Happy playing!
