Problem Description

Issue

Hi, I recently tried to make a modded minecraft server with FTB Stoneblock 4 but once I input all the needed data then hit update to grab the server files most made it back to the file manager but when I hit start it said server.jar was missing. Thank you for your help!

Reproduction Steps

  • Tried a normal vanilla minecraft server and that came with the server.jar so it worked
  • I deleted the vanilla java instance and tried again the exact same way with the ftb new server (ftb stoneblock4) and still no server.jar
  • I then tried other mod packs within that ftb new instance and no other mod pack came with the server.jar
