Problem Description

Issue

My server was unreachable this morning. Investigating the problem has shown me that Amp is looking for the wrong version of NeoForge. I can’t select the version in the drop down that I already have installed. I’ve tried to manually select the jar but I am unable to do that as well. Amp will only show me versions of NeoForge for 1.20.1. I need a version for 1.21.1.
I am unable to start my server because it queries the wrong version of NeoForge

Reproduction Steps

  • Shut Down and backed up the server via schedule
  • Tried to restart and failed
  • Amp switched the version of Java to 25 from 21 on its own
  • Amp can not see a version of NeoForge for Minecraft 1.21.1.
  • Amp tried to start but is looking for the wrong version of NeoForge
